Since V 9.407-3 emails with same to-recipient  and cc-recipient will stuck in mail manager in SMTP Corrupt.

Why does the mail stuck and will at least not be sent to the recipient once?

  • There is also one other issue that has not been mentioned or I have not seen.

    If an email address is repeated it will also "get stuck" in the smtp corrupt.

    I have an application that will combine email addresses from different accounts when sending an email

    So if an address exists in the TO: CC: more than once, it will screw up the "count"

  • It's a new perspective on this matter but yes, still the same, two or more adresses that are the same in the same mail is screwing the counters up :-O

  • I don't think it happens with all mail servers and clients.  If you put the latest patches on your mail server, you might want to keep an eye on this.

  • Running Exchange 2016 Cu3 at home, have no problems either, but if I use a SMTP test tool, aka. 3-party mailer (CRM/HR/ERP), things get stuck :-)

     

    It's how the thing are delivered, Exchange handles duplicate emails in another way, and yes, I have Exchange sending the mails through my UTM :-)

     

    Try this:

    Then write the same address in TO and CC and watch the "magic" :-)

    Same here, I think it's supposed to work that way, at least it did also like this with 9.404, Exchange "consolidates" the messages when receipient is the same :-)
