2.6 Kernel and POP issues

[Robert T. Covell]

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...

 

-Thanks

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.
