And additionally DKIM and DMARC entries would also be favourable

  • smtp server service
    Hello list,

    We use our Odoo extensively to send our emails. I just did the stats and 75% of our sent emails are from our Odoo.
    We are currently using gmail as our smtp service. We start to see some of our emails tagged as spam. We are wondering why.
    Have you ever faced the same problem?

    Another question on the same topic, what do you use as SMTP service ? Would you advise to go to a simple local server or to go to a dedicated service provider like mailgun or something like that?

    Again, thank you for all your answers. You are the best :)
    Take care.

    Jordi

      Hi Lorenzo,

      I'll look into installing mail_outbound_static on odoo-community.org.

      -sbi

      Below an example of email to "contributors@odoo-community.org" marked as SPAM because of failing DMARC.

      Can someone install it? Then you just need to set the fixed "from" address in the ir.mail_server, like "mailing@odoo-community.org"

      Thanks!

      Hi Jordi,

      Odoo is not DMARC compliant. You can check the issues reported by Oleg for some history:

      In order to avoid messages sent by odoo to be marked as SPAM because of DMARC, you can use mail_outbound_static

      By the way, we use Mailgun too.

      Hello Community!

      Thanks again for the feedback.
      We put in place SPF, DKIM and DMARC policies.
      We need not to work them out so the emails sent from odoo are greenlit.

      I am falling deep into the DMARC reports :)

      Hello, Jordi,

      1. First of all you need to tell us how you setted up your Odoo to work via Gmail? And also what is version of Odoo you are using ?

      2. Also are you using standard Odoo capabilities of sending emails or you customized smth? Reason, standard Odoo works like this.
      - Imagine I have sent email to your email sales@yourdomain.com from my email address oleg@mydomain.com
      - A new opportunity is created that will send emails to all followers of sales team sales@yourdomain.com is mail alias to.
      Important! Odoo Standard will send email to followers FROM oleg@mydomain.com

      So actually it will be sending email from domain it is actually not controlling.

      Few things about it:
      - Generally speaking we do not know(nobody knows) if google likes when you do that way. My personal opinion is by doing that too often , you Gmail domain will loose ratings.
      - second thing - if on my email domain  oleg@mydomain.com DMARC is properly configured, than google will not send it. Because that is SPAM! Obviously it is spam when you try to pretend sending from not your domain 

      Just read this for more details. This is ongoing discussions in many other Odoo issues on GitHub (just quick Google) 

      Usually Olivier Dony is participant of this discussions as he is expert in this. You can find a lot of issues like this from Odoo side.

      So another important recommendation. Do not mix different type of emails in one provider.

      There are 3 types of mails you usually send:
      1) Personal - use Google apps for sending personal emails. Because that way you make sure this mails are isolated from other type of mails and your mailbox will not be marked as spammy because you sent content from Odoo through relay and some systems report it as non reliable and spammy(for different reasons). So sending your emails from Odoo through Gmail you have a risk that even your personal emails will become untrusted and will get into spam.

      2) Transactional mails - this is mails from Odoo, other automatic messages (like registration confirmation ). Use for this separate specialised transactional mail provider . Like mailgun. Simply for reason in point 1. "Do not place eggs in one basket"

      3) Mass mailing - never do it through Odoo that sends it through Gmail. Despite of the fact Odoo has mass mailing feature  you will compromise your domain very easily with mass mailing if use Gmail.  If you still want to use Odoo mass mailing, configure separate outgoing mail server for this (for example through mailgun or other transactional provider) 
      Or better, Use specialised massailing providers like Mailchimp for this. Because after reputation of your domain is lost it is very hard to restore it. So you will be getting into Spam even from your personal mails.

      Few things:
      1) If you do not have full time sys admin, do not setup your own mail server. It is very hard to maintain mail infrastructure as new mail server need to get good reputation before other mail providers will trust it. And that is long process. And with sending mails from Odoo through your vanilla installed postfix you will not get good reputation easily. Most likely you will get anti-reputation :)
      2) check your domain is not blacklisted 
      Reason , most mail providers when receiving mail automatically check for blacklists. And if it is blacklisted, it can be marked as spam.
      3) make sure DKIM is setted up properly on your domain 
      4) Make sure that SPF is defined for all your mailproviders you are going to use (Gmail, Mailgun, MailChimp and etc.). Every such mail provider has dedicated page how to configure this.
      5) DMARC yes, configure it also for stronger validation. Note that Odoo work bad with DMARC configured emails. There were few attempts like below from Community to fix behavior of Odoo , but it was always non accepted https://github.com/odoo/odoo/pull/20911

      Hope that all helps !

the relative amount of mails going through Odoo is probably less

probably going through an load balanced and properly scaling service

      Hi Jordi,

      Odoo is not DMARC compliant. You can check the issues reported by Oleg for some history:

      In order to avoid messages sent by odoo to be marked as SPAM because of DMARC, you can use mail_outbound_static

      By the way, we use Mailgun too.

      Regards

      Hello Community!

      Thanks again for the feedback.
      We put in place SPF, DKIM and DMARC policies.
      We need not to work them out so the emails sent from odoo are greenlit.

      I am falling deep into the DMARC reports :)

      Hello, Jordi,

      1. First of all you need to tell us how you setted up your Odoo to work via Gmail? And also what is version of Odoo you are using ?

      2. Also are you using standard Odoo capabilities of sending emails or you customized smth? Reason, standard Odoo works like this.
      - Imagine I have sent email to your email sales@yourdomain.com from my email address oleg@mydomain.com
      - A new opportunity is created that will send emails to all followers of sales team sales@yourdomain.com is mail alias to.
      Important! Odoo Standard will send email to followers FROM oleg@mydomain.com

      So actually it will be sending email from domain it is actually not controlling.

      Few things about it:
      - Generally speaking we do not know(nobody knows) if google likes when you do that way. My personal opinion is by doing that too often , you Gmail domain will loose ratings.
      - second thing - if on my email domain  oleg@mydomain.com DMARC is properly configured, than google will not send it. Because that is SPAM! Obviously it is spam when you try to pretend sending from not your domain 

      Just read this for more details. This is ongoing discussions in many other Odoo issues on GitHub (just quick Google) 

      Usually Olivier Dony is participant of this discussions as he is expert in this. You can find a lot of issues like this from Odoo side.

      So another important recommendation. Do not mix different type of emails in one provider.

      There are 3 types of mails you usually send:
      1) Personal - use Google apps for sending personal emails. Because that way you make sure this mails are isolated from other type of mails and your mailbox will not be marked as spammy because you sent content from Odoo through relay and some systems report it as non reliable and spammy(for different reasons). So sending your emails from Odoo through Gmail you have a risk that even your personal emails will become untrusted and will get into spam.

      2) Transactional mails - this is mails from Odoo, other automatic messages (like registration confirmation ). Use for this separate specialised transactional mail provider . Like mailgun. Simply for reason in point 1. "Do not place eggs in one basket"

      3) Mass mailing - never do it through Odoo that sends it through Gmail. Despite of the fact Odoo has mass mailing feature  you will compromise your domain very easily with mass mailing if use Gmail.  If you still want to use Odoo mass mailing, configure separate outgoing mail server for this (for example through mailgun or other transactional provider) 
      Or better, Use specialised massailing providers like Mailchimp for this. Because after reputation of your domain is lost it is very hard to restore it. So you will be getting into Spam even from your personal mails.

      Few things:
      1) If you do not have full time sys admin, do not setup your own mail server. It is very hard to maintain mail infrastructure as new mail server need to get good reputation before other mail providers will trust it. And that is long process. And with sending mails from Odoo through your vanilla installed postfix you will not get good reputation easily. Most likely you will get anti-reputation :)
      2) check your domain is not blacklisted 
      Reason , most mail providers when receiving mail automatically check for blacklists. And if it is blacklisted, it can be marked as spam.
      3) make sure DKIM is setted up properly on your domain 
      4) Make sure that SPF is defined for all your mailproviders you are going to use (Gmail, Mailgun, MailChimp and etc.). Every such mail provider has dedicated page how to configure this.
      5) DMARC yes, configure it also for stronger validation. Note that Odoo work bad with DMARC configured emails. There were few attempts like below from Community to fix behavior of Odoo , but it was always non accepted https://github.com/odoo/odoo/pull/20911

      Hope that all helps !

      A few keypoints:
      • Try having DKIM,SPF and DMARC
      • Make your signature on Odoo a text instead of an image (just in case your Odoo signature is different)
      • Use GMAIL relay server smtp-relay.gmail.com; just in case you're hitting your quota (not related to SPAM tough)
      • Amazon Simple Email Service is great for mass mailing https://aws.amazon.com/ses/

      Hi Jordi, 

the relative amount of mails going through Odoo is probably less
relevant than the absolut amount. Generally spoken i'd always suggest
to invest time in setting up an own mail Server instead of relaying
through GMail and if you really need to sent masses of uniform E-mail
probably going through an load balanced and properly scaling service
like mailchimp or mailgun would be devisable yes. I don't honestly know
but E-Mails going through Odoo will be easily identifiable by almost
every AI and that is probably the reason (in relation with the content
of the mails) being identified as SPAM

Best Frederik

Hello Jordi,

We use https://www.mailgun.com/ with over 150.000 mails / month. Mailgun
takes care about that.

99.35% delivered
0.64% bounced
0.01% suppressed.

All the tracking info is inside Odoo thanks to
https://github.com/OCA/social/tree/12.0/mail_tracking_mailgun

     - Depends on https://github.com/OCA/social/tree/12.0/mail_tracking
     - Also nice
https://github.com/OCA/social/tree/12.0/mail_tracking_mass_mailing

So when someone tag as SPAM you (or your customer) can fix it.

Asunto: smtp server service

Hello list,

We use our Odoo extensively to send our emails. I just did the stats and 75%
of our sent emails are from our Odoo.
We are currently using gmail as our smtp service. We start to see some of
our emails tagged as spam. We are wondering why.
Have you ever faced the same problem?

Another question on the same topic, what do you use as SMTP service ? Would
you advise to go to a simple local server or to go to a dedicated service
provider like mailgun or something like that?

Again, thank you for all your answers. You are the best :) Take care.

Jordi
