Could be name resolution. What's in your /etc/resolv.conf ?

Very possibly the
same problem. What RBLs are you using?

This may be
my problem also. My spamdyke filter started timing out bigtime but when I
removed the spamdyke, it still takes the smtp server about 30 seconds to answer
when I telnet to port 25.

Strange problem : smtp become really slow
Hi,
this morning a strange
problem start on my qmailtoaster server, the SMTP
service become really
slow.
Al the other service (pop3, imap, submission port)
are still ok.
I've restarted a couple of times the server and I tried also to
disable
rbls, spf, spamdike, clamav and spamassassin but nothing changed.
There
is nothing strange in the logs, and I haven't done any update or modification
on the server.
If i try to connect to the port 25 with a telnet session
the
connectiion is established quickly but when I type helo no response
comes from
server, only a couple of minutes later it will respond to the
command ....
From
my test seems that the problem deal with CHKUSER wich
is really slow (from the
smtp/current log I see that there is a big delay
between the accepted
connection and the chkuser response) but I don't know
how to investigate
further.
