A more complete log (this is an older version of postfix that doesn't
log in the same format, but it can be seen where the delay is) is at
http://pastie.caboo.se/private/7sskrugsfbuw1slgpf
It can be shortened to this:
Mar 1 13:24:59 mta7 postfix/lmtp[18735]: >
box2.prv.f3.k8.com.br[10.8.5.49]: .
Mar 1 13:30:07 mta7 postfix/lmtp[18735]: <
box2.prv.f3.k8.com.br[10.8.5.49]: 250 2.1.5 Ok
Mar 1 13:30:07 mta7 postfix/lmtp[18735]: 4325B3800084:
to=<user2=>,
relay=box2.prv.f3.k8.com.br[10.8.5.49], delay=309, status=sent (250
2.1.5 Ok)
After postfix sends the ".", it takes lmtpd more than 5 minutes to send
the "250 2.1.5 Ok" back (everything else on the lmtp conversation
happens in the same second). Is this the time when lmtpd writes the
message to disk? I'm trying to find out if I/O is really the bottleneck
here.
Thanks,
Andre
