I've searched the postfix-users list and as expected I'm not the only one to see this issue: http://marc.info/?l=postfix-users&m=120168533827364&w=2 Since postfix (and I think also other MTA's) are a bit relaxed on what they accept as "MAIL FROM:" addresses, is there a very good reason for Cyrus to be so strict?
