Another debian urgh moment: This time postfix

I've been tracking down a problem when trying to use gmail's smtp server for relaying.

We are using debian and post fix.

Errors like the following appear:

certificate verification failed for[]:587: untrusted issuer /C=ZA/ST=Western Cape/L=Cape Town/O=Thawte Consulting cc/OU=Certification Services Division/CN=Thawte Premium Server CA/
warning: SASL authentication failure: No worthy mechs found


The fix on debian:

apt-get install libsasl2-modules

That's right.  When you have SASL installed on debian you also need to install the authentication mechanism modules.  Great.


I'll update this post with instructions on how to get your debian MTA server to relay to gmail.
