DELETE log_on_success AND log_on_failure!
Authored by: JohnAlbin on Apr 16, '03 05:53:43PM

From UW IMAP’s FAQ (

7.24 Why is there a long delay before I get connected to the IMAP or POP server, no matter what client I use?

[...] look for lines containing "USERID", e.g. log_on_success += USERID

Hunt down such lines, and delete them ruthlessly from all files in which they occur. Don't be shy about it.

The USERID attribute causes xinetd to do a IDENT lookup on the client. “The IDENT protocol is a well-known bad idea that does not deliver any real security.” IDENT is (thankfully) not enabled on almost all clients, so adding the log_on_success += USERID and log_on_failure += USERID lines causes a slow-down of the imap server with no benefit.

You can still add log_on_success += DURATION if you want. But, unless you plan on reading your syslog for XINETD messages, there’s no point.
