I'm running an Amazon linux AMI and using sendmail as the mail server. By default, STARTTLS is disabled on this build and I'd like to enable it for SMTP and POP3. I seem to have it configured properly for SMTP, but in order to get the POP3 auth to work I think I need to reconfigure sasl2 so it accepts a few other auth mechanisms (DIGEST-MD5 and CRAM-MD5).
The default sasl2 install was built using the AMI's yum repo, and i think I need to reconfigure it with a few additional options. What's the best way about doing this? Should I just
yum remove cyrus-sasl2 and then compile from source, or is there a quick and easy way to reconfigure a yum-installed app?
