Hello Tom,
Hi,
I do not have access to the web application but I tried the debuging
option now and send you the output. I also make an external check and
foud out that the connection time is very high. Maybe this is the
problem but I do not understand this because the system is reachable
as normal.
SMTP Connection Time 5.912 seconds
SMTP Transaction Time 8.440 seconds
These numbers are quite high, yes. The web application probably hits a
timeout
before the connection is established.
This attempt was made from the web application's host?
Did you also try a manual handshake test with telnet? Would be
interesting to
know at which stage these long waits occur.
What about Wireshark? Were you able to analyze a network trace?
Exim version 4.82 uid=0 gid=0 pid=4897 D=fbb95cfd
[...]
4901 doing ident callback
4901 ident connection to x.x.x.x failed: Connection timed out
You probably should disable ident lookups, I don't see why anyone would
need
those today and by doing so you get rid of a few seconds of waiting.
What's rfc1413_query_timeout set to in your configuration? Maybe this
explains
the ~6 seconds connection time.
Apart from that I cannot find any issues in this debug trace.
Bye,
Tom.
