This afternoon a user complained about missing email and mentioned that the sender "is not getting a bounce". In the logs I see several iterations of:
Oct 10 09:51:42 aegis postfix/smtpd[52803]: timeout after DATA (256605 bytes) from relay.airtiger.com[63.170.171.120] Oct 10 10:09:56 aegis postfix/smtpd[53022]: timeout after DATA (3240605 bytes) from relay.airtiger.com[63.170.171.120] Oct 10 11:09:36 aegis postfix/smtpd[53463]: timeout after DATA (2998025 bytes) from relay.airtiger.com[63.170.171.120] The sending server is re-trying every hour and the sending user will probably get a bounce once the other MTA gives up. I just want to make sure there isn't anything I can do on my end to help this mail through?
