I don't know. It was just my understanding that this was the way it worked. Or: that the bounce address was specifically generated per message - and that the "-XV" option to sendmail was the mechanism for triggering this behaviour. The VERP_README says: > In order to make VERP useful with majordomo etc. mailing lists, you would > configure the list manager to submit mail according to one of the following > two forms: > > Postfix 2.3 and later: > > % sendmail -XV -f owner-listname other-arguments... Can I use VERP without specifically generated bounce addresses? How do I then identify the problem adressee - which possibly has a mutated address? Best regards keld
