I had a server running on gentoo and it was running OK, but the latest updates in the gentoo tree killed it. So I spent yesterday afternoon setting up new mail server using Ubuntu 12.04 LTS.
It took a while, but I have it all working except for smtp authentication (which was working on the gentoo machine. I copied the configuration over to the new machine and now I'm getting the following error: warning: SASL authentication problem: unable to open Berkeley db /etc/sasldb2: Invalid argument according to the redhat website that tells me that it is because postfix is linked against the wrong version of berkely db. https://bugzilla.redhat.com/show_bug.cgi?id=734088 However, nothing in my configuration says to open the sasldb file anywhere as the auth machanism is set to imap, but postfix seems intent on opening this file anyway. smtpd.conf: pwcheck_method: saslauthd mech_list: PLAIN LOGIN #auxprop_plugin: imap Does anyone have any ideas?
