Hey guys,
                As a server receiving client connections from another
network, I am seeing "timeout after DATA" errors. The problem seems to be
isolated to one particular mail network, so Im _fairly_ confident that my
systems are koshure.
Using debug_peer_list I have scoured through debug output and can see that
we are receiving no "." to end the DATA phase from this mail network.

What I would like to clarify is some of the timeout settings.. Being a
server side connection I was under the impression that the entire connection
was bound by the smtpd_timeout parameter? And not the specific
smtp_data_xxxx_timeout settings.

-------
# postconf | grep smtpd_timeout
smtpd_timeout = 300s
-------

However I am seeing these timeout messages sometimes only 30 seconds after
the intitial smtpd connection, not 5 minutes:
