I had posted this previously to the list and got some replies back on
what I can do to fix the problem. I raised the number of connections
that tcpserver would accept. I got another e-mail from the same user
saying he is still every so often getting this error. This isn't
something qmail is sending him this is a dialog box that netscape is
showing.
To refresh your memory briefly, a user of mine is getting an error from
netscape comm. mail client 4.7.1 please try again later. No one else
has said anything about this happening to them and the mail flow is
quite consistent.
After monitoring this I think I have found the problem but I want to
make sure.
I noticed a lot more e-mail activity lately and noticed people are
sending to 5, 10, 15 people at a time. You get a couple people doing
that and the 20 connection limit in qmail's smtpd is pegged until it can
deliver the mail. I went through the log again looked for the date's
and times he couldn't send mail and noticed that there pending remote
deliveries of 20/20, 20/20, 20/20 . Which was odd because the number of
deliveries never went down. I looked through log and found that a quite
a few people had sent e-mail's to 5 and 10 people at a time and some of
those mail servers were deferring connections. I noticed the it was
possible that he was trying to send at a time when the queue was 20/20
and when he waited a minute or so the queue went down to 19/20 which
allowed him to send.
If this is so can i raise the number of connections? I don't like
re-compiling binaries once I got everything working fine, tempting fate
it to easy. ;)
Thanks in advance,
