I have Red-Hat 6.1. After I have installed the package imap-4.5-4 and
modified the file /etc/inetd.conf (i have enabled the lines pop2 - pop3 -
imap) i have enabled sendmail. After that in my /var/log/messages there is
the following error : auth/tcp: bind: Address already in use. The message
continues every 10 minutes. I have try to go back but the message remain.
Verify that the new changes (probably in /etc/inetd.conf.rpmnew) are merged.
The files is marked %config(noreplace), which basically means that we (Red Hat)
will never change the file, so the merge is up to you.
The problem comes from starting up 2 instances of in.identd which are squabbling
over the port. For Red Hat 6.1, indets startup of in.identd is the preferred
method, but see also your alternatives in /usr/doc/pidentd*.
