Hi, we have two qmail servers runing as mail gateways, recive mail for
mydomain.es and forward it to an internal mail server, this morning the
firewall between the mail gateways and the internet go down ten minutes,
and qmail lost all connectivity, (can't send mail to the internal mail
server and can't send mail to the Internet) when the firewall go up and
qmail have connectivity it start reciving mail for mydomain.com but don't
forward it to our internal mail server, the log say qmail: 967616885.541933 delivery
481922: deferral: Sorry,_I_wasn't_able_to_establish_an_SMTP_connection._(#4.4.1)/
but if I open a telnet connection from the qmail server to the por 25 our
internal mail sever I can send mail, looking at the firewall logs I can
see that qmail isn't starting any connection to our internal mail server
but say Sorry,_I_wasn't_able_to_establish_an_SMTP_connection._(#4.4.1)/
the internal mail server forward mail to the qmail server and qmail server
send it to the internet, but don't forward the mail he revice fron the
Internet to the internal mail server just put it in the queue and log
Sorry,_I_wasn't_able_to_establish_an_SMTP_connection._(#4.4.1)/, whitout
open any qmail-remote processes to send mail to our internal server.
I tryed to send a kill -ALARM to qmail-send but the problem persist, I
tryed to send a kill -HUP to qmail-send but the problem persist, after
stop qmail-send and restart it all run fine, qmail is sending the mail to
our internal mail server, anyone experienced the same problem or have any
idea of what is causing the problem.
The two servers experienced the same problem and the problem has gone when
I restart qmail.
The qmail version is 1.03, runing on Debian GNU/Linux 2.2 with a 2.2.16
Kernel.
Thanks, and sorry for my bad english.
