Check if some firewall is silently dropping identd requests to port 113, as some earlier posting said. This might cause a timeout to the identd request of the other side, although I'm not sure if it's just 5 sec. Then check if your sendmail has the RBL feature enabled. This contacts a remote name server, and can cause some delay. Alas, even a caching named will not solve the problem if you find that this is the cause. I found out only recently (before I tried qmail for a while) that when I disabled RBL and wrote a proper /etc/mail/access map to control relaying from my dialup connection, my sendmail became a bit faster in it's responses. -- Giorgos Keramidas, < keramida @ ceid . upatras . gr > For my public PGP key: finger keramida@diogenis.ceid.upatras.gr PGP fingerprint, phone and address in the headers of this message.
