RE: [cobalt-users] [Qube 3] Mail Sending Problem

["[C] Paulick, Jim" <jpaulick@xxxxxxx>]

try looking in the sendmail.cf  configuration file.  check all timeouts, and set them to 0s.  This may not be the same problem that I had, but it may be related.  

/etc/mail/sendmail.cf

#O Timeout.quit=2m
#O Timeout.misc=2m
#O Timeout.command=1h
O Timeout.ident=0s
#O Timeout.fileopen=60s
#O Timeout.control=2m
O Timeout.queuereturn=5d
#O Timeout.queuereturn.normal=5d
#O Timeout.queuereturn

notice the tiemout.ident=0s.  I had to change that simply because when we put our new firewall in place, it just dropped the ident request packets instead of responding with null or something else more helpful.

hope it helps.

->-Hi,
->-The first thing I'd try is to re-recreate the problem more 
->-frequently if
->-possible. Try from one of the affected users machines, and 
->-telnet to the
->-qube's port 25
->-(on an ms system, just start > run and type in telnet 192.168.0.1 25)
->-See how quickly it responds and issue a HELO command and see 
->-how long it
->-responds.
->-This helps you determine whether it is indeed the network/sendmail on
->-the Qube or whether it's the windows client slowing up on 
->-its connection
->-time.

	Had tried that, but did it again just for the hell of it, it
takes from about a minute to 2 minutes for it to start working so I can
type in the HELO command

Here is the ps showing that it is starting up but sitting there for a
while.  It goes into startup almost immediately, but then sits there for
a while.

root     29048  0.0  0.9  2492 1228 ?        S    10:00   0:00 sendmail:
accepting connections
root      4574  0.0  0.9  2508 1260 ?        S    11:46   0:00 sendmail:
startup with 192.168.1.76

And then after about 1 to 2 minutes you can see it goes into command
mode, or however you title it in the sendmail world. =)

root     29048  0.0  0.9  2492 1228 ?        S    10:00   0:00 sendmail:
accepting connections
root      4574  0.0  1.2  2652 1552 ?        S    11:46   0:00 sendmail:
server [192.168.1.76] cmd read
admin     4673  0.0  0.3  1208  416 pts/2    S    11:48   0:00 grep
sendmail

Thanks, any more things to check?
