Title: RE: 2.6 Kernel and POP issues
As of this time I am happy to report that adding
“--with-devrandom=/dev/urandom” to the sasl config has solved the
issue for a 2.6 kernel. I was finally able to implement the compile time
feature last week and “seem” to be running fine.
Just a follow-up to the thread…

Well it figures that I recomplied cyrus
imap only and NOT sasl. I will recompile that and put in the allowapop
statement. Report to follow...

Well, recompiling SASL *should've* taken care of that, but you could also
try disabling APOP in /etc/imapd.conf:
allowapop: 0
Restart Cyrus after you make the change. If that helps it means that, for
whatever reason, Cyrus still uses /dev/random instead of /dev/urandom ...
if it doesn't help, something else must be wrong. I have no idea what that
might be.
