    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.
