When the user is trying to send mail he gets this error in a regular
windows type dialog box in netscape "mail server responded 4.7.1 please
try again later. Please verify that your email address is correct in
your mail preferences and try again". He waits a little while and tries
again and it will go through fine. Could you post the smtp error
codes?
>From what I was able to gather is this. I have noticed that the
concurrencyremote in my log is at 20 quite a bit. You would see
deliveries like 20/20, 20/20, 20/20, 19/20, 20,20, 20,20 19,20 it seems
like when it delivers a message it gets another one to deliver.
Depending on the back log it could take a couple hours to get the count
below 20. I compared the times that he couldn't send and found that
Tcpserver is logging his ip and connection but qmail-smtpd deffers his
connection apparently because I never see a message injected at that
time/date. I also noticed that it has been in between times where there
is a heavy back log of mail (where the concurrency for remote was 20/20
for an extended period of time) which meant his mail wasn't accepted
because it was already at 20 connections. I have seen in the log where
the delivery numbers ( I made sure they were the same e-mail, saw that
qmail will reuse deliver numbers) are back quite a bit. For example
messages 504 to 517 are injected mean while delivery 483 was just
completed....so there is a back log of 30 some messages.
I am going to get qmail-mrtg and see what it says about my maillog
hopefully in more detail that I can do with grep and joe (wordstar like
editor for unix) vi just got to annoying to me but works in a pinch.
