How to tell postfix to quit sending the same mail over and over again

[Chris Fleming]

I would start by looking at postfix queues:

mailq - will list everythings in queues. You can delete using

postsuper -D

Also I presume that you've checked the mail logs, to see if there are
any clues?

Cheers Chris

  Hello fellow Kolab users,

  I'm struggling with a serious problem here.

  One of my users sent a very large e-mail (round about 32m) to a
  business partner of us. All went as expected. But my server won't stop
  sending this particular mail. I already deleted it from the users
  mailbox (via bash and via roundcube) nontheless the floodgates are
  still open and roughly all 15 seconds our business partner receives
  this mail.

  Till now he's a good sport about it, but I'd rather stop his agony and
  put an halt to this.

  But I have no clue from which service/directory/whatever this e-mail
  gets pumped into postfix.

  ANY hints where exactly to look and how I can stop this behaviour is
  HIGHLY appreciated from my side.

  Server: CentOS7 System and Kolab fully patched.

  With kind regards

  Torben Mohrfeldt
