Hi, since fedora core 4, I have a problem with postfix. Postfix sends small messages but great messages (>64 KByte) are not send. The logfile /var/log/maillog says: postfix/smtp[18886]: A741C10DACB: to=<aaron.pohle@xxxxxxxxx>, relay=mail.gmx.de[213.165.64.20], delay=206, status=deferred (conversation with mail.gmx.de[213.165.64.20] timed out while sending message body) With kontact I can send large messages directly to mail.gmx.de but this is no solution for me. Have somebody any idea what the problem is? Thanks, Aaron
