[Fetchmail-users] Weird Return-Path processing

[Skle.pik <sp...@ma...>]

Hi,  I've been using fetchmail for quite a while without any complain whatsoever, but recently I found some of the messages not to be delivered.  The investigation of processing for not delivered mails shows Return-Path to be split to 2 lines:  Return-Path: <noreply=  abba.com__al4bl7qh36xreia2@35p  11.bnc.salesforce.com>  Delivered-To:   Unfortunately this makes mailer choking:  SMTP> MAIL FROM:<noreply=  abba.com__al4bl7qh36xreia2@35p  11.bnc.salesforce.com> SIZE=4070  SMTP< 553 5.0.0 ....   Does anyone know who is to blame - is this Return-Path formatting violation on POP side, or maybe it is mailer being intolerant ?   Cheers
