Title: Increase Default SMTP timeout???SOLVED incorrect DNS setup. Post by: turitopa on Thursday 10 February 2011, 09:45:04 am Hi,
I am getting some 4.4.2 errors with some outgoing mail. Please refer to Log extract below. Code: Feb 8 08:24:11 ***** postfix/smtp[27636]: DE365DE104: to=<*****@yahoo.co.uk>, relay=mx1.mail.eu.yahoo.com[77.238.177.9]:25, delay=430024, delays=429643/0/184/197, dsn=4.4.2, status=deferred (lost connection with mx1.mail.eu.yahoo.com[77.238.177.9] while sending end of data -- message may be sent more than once) Or should I adjust my MTU settings? Any else notice this? Please advise... btw I am running SBS2008, exchange 2007 on a Xenserver. Title: Re: Increase Default SMTP timeout???

I am also trying to change the 'smtp_data_xfer_timeout' setting in /postfix/main.cf I restart postfix to affect the change but it just removes the entry I added and stays at the default of 180s.

I had not setup send connectors correctly. I repointed my Exchange server Send-connector to EFW smarthost(no auth), then on EFW connect to smarthost of my ISP send connector (isp Auth). I also changed my DNS setup on my DC. I had listed EFW box as a secondary dns for the network device on the DC. i removed that so now only DC DNS and setup conditional Forwarding to my EFW and ISP DNS. Previously i was sending direct from exchange to internet. If that makes any sense, but yes i no longer have any 4.4.2 errors in my immediate logs. Knock on wood. Hope this helps you. EDIT: btw i have disabled Virus scan of SMTP proxy, and 4.4.2 disappeared. Therefore my CLAM AV is malfunctioning but i just bypass it now, not the best solution but it works. |
