<p style='color:#333; font-family:Georgia, Verdana, "Times New Roman", Times, serif; font-size:16px; font-weight:normal; margin-top:10px; padding:0'>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.</p>

<p style='color:#333; font-family:Georgia, Verdana, "Times New Roman", Times, serif; font-size:16px; font-weight:normal; margin-top:10px; padding:0'>But I have no clue from which service/directory/whatever this e-mail gets pumped into postfix.</p>
