    Hi,

    I have an exim problem. Exim is retrying a mail that receives 550 at RCPT TO field. How do I fix this behavior?

    Code:
    Connecting to dpexh.digiturk.com.tr [212.252.206.1]:25 from 209.xxx.xxx.xxx ... connected
      SMTP<< 220 Welcome...
      SMTP>> EHLO host.xxxxxx.com
      SMTP<< 250-Hello host.xxxxxx.com, pleased to meet you
             250 SIZE
      SMTP>> MAIL FROM:<> SIZE=111333
      SMTP<< 250 <> SIZE=111333 ... Sender ok
      SMTP>> RCPT TO:<DIGITURKMEDYA.PAZARLAMA@digiturk.com.tr>
      SMTP<< 550 Mailbox unavailable.
      SMTP>> QUIT
    LOG: MAIN

    Go on, have a guess
    Is dpexh.digiturk.com.tr your server? If not, then it's a remote SMTP error, i.e. the error is coming from that server and the problem lies there not with your server. If that is your server, you need to check the exim logs.

    No it is not. My problem is this mail is trying to be sent over and over again as I retry. I am seeing similar wrongly done retries to 5xx errors. It is not limited with those null senders... here is a sample:
    and another:
    wow.. this one suddenly removed itself. the one above is still retriable... strangely..

    what could be the cause of this 5xx error retrying

    To clarify, is your expectation that a 550 response from the receiving server should bounce back a message to the original sender (like User Unkown) vs. leaving the message in the queue for retrying?

    Yes. Exactly... The to-be-sent mails are in my queue but they are re-tried after some time to check weather they are deliverable or not... even if they get a 550 error, they are blindly re-tried over and over again.

    It is really strange that all of my waiting messages are null (<>) sender... But I have seen some non-null senders waiting too..
