Using Red Hat Linux 7.2 (enigma) Kernel 2.4.7 on an i686, and the version of Sendmail and BIND that came with it (revised May 2002).

When POP3 E-mail requests go to this host, it requests and auth (port 113) response. Since the clients accessing mail do not have authentication running, the host waits for the default 30 seconds, retries, waits for another 30 seconds, then finally gives up and delivers mail.

In the older versos of Red Hat Linux, auth was served by a process called Identd, which could be either deactivated for POP3, or you could set its timeout to practically nothing (instead of 30 seconds).

In this new version of Linux, it appears that xinetd (note spelling....it is not a transposition on my part) has supplanted identd. However, it is no longer an option for POP3....xinetd manages POP3 connections (as well as others) and apparently can't be unbound. There also seems to be no apparent way to set the timeout way low for the auth queries.

I need to know if there is a way to tell Sendmail not to use auth. I understand there is, but I'm having a heck of a time finding it. Thanks.

I'm assuming your /etc/xinetd.d/ipop3 configuration looks something like this:<br><blockquote><code>

service pop3
{
disable = yes
socket_type = stream
wait = no
user = root
server = /usr/sbin/ipop3d
log_on_success += USERID
log_on_failure += USERID
}
</blockquote></code>

Add a "#" before each "log_on" line, which has been causing the 30-sec delay. This is a decision on the administrator's part to decrease the quality of his or her logging for that service so that your users may get their mails quickly.
