All, We would like to share some experience related to the merge AOL and Yahoo; this could impact your PMTA and email delivery in general.
Thanks, Willem - Postmastery

Because they are showing as delivered in PowerMTA, there isn't too much we can do.  Once the message has been received by the remote mail server, it is out of our control what happens to it.  However, I would largely suspect this is a reputation/content issue.  You may want to verify double-opt in verification of your email list, remove any bounced emails from your list, and verify that your content looks good and is requested by members of your list.

Hello Admin thank you,

Nowaday we are sending test emails.

I reached the following conclution:  It happend when we send multiple emails in few seconds and them have the same content, subject and are sending to the same rcpt.

I hope this information help the community.

Thank you!

Hello there,

We are sending multiple transactional emails to Gmail, Hotmail and Yahoo.

Gmail/Gsuit and Hotmail/365 have deleted all emails or I can't see at inbox/spam/promotions, etc, only one was delivered for each of them but when I send emails to yahoo all are delivered correctly and I can see all of them at inbox.

Could you please tell me why it happend? I have attached a screen capture in this thread.

Thank you!

Hello,

Thank you for the whole information.

We have a large amount of domains signed with our postfix dkim signature.

Is it possible use one .pem file to all domains?

Thank you!

Instructions on the setup of DKIM records and signing can be found in section 10.4 of the User's Guide, and you can use our DKIM Wizard (highly recommended) for the first time. The wizard can be found here:
http://www.port25.com/support/domainkeysdkim-wizard/

If you are using our wizard, you'll need to enter the TXT record into your DNS record for the public key as outlined in the wizard, and then save the private key to the PowerMTA server. 

Then, you'll need to add these two directives:
domain-key
dkim-sign yes


It will look like this in your config:
Code: [Select]
domain-key key1, yourdomain.com, C:\pmta\key1.somedomain.com.pem

<domain *>
  dkim-sign yes
</domain>

Make sure the path to the private key is valid, save config, and then reload. If DKIM doesn't work after ensuring the above is done, send a message to our auth-checker tool ( https://www.port25.com/authentication-checker ). It will reply with a report that includes reading a DKIM signature. If there is indeed a DKIM signature in the message, then the issue very likely lies outside of PowerMTA (likely DNS not yet or incorrectly set-up, wrong selector for it, etc.). Feel free to have the support team review the report by sending it to support@port25.com

*You may reuse the public/private key from Postfix into PMTA.

Hello there!

I'm working in our DKIM signature this quarter and I need to understand the best way to get one DKIM signature and migrate to PMTA.

Do you have any experience migrating from Postfix to PMTA?

Thank you!

Sure, just add the following globally:

name-server 8.8.8.8
name-server 8.8.4.4

Once added, reload PowerMTA with "pmta reload"

Hello Admin, thank you!!!
