I uncommented the "submission" section in /etc/postfix/master.cf, and my firewall is open on port 587.
I get the following error when trying to submit a message via port 587 with TLS:
Sep 30 13:41:05 mailer postfix/smtpd[7577]: warning: SASL authentication problem: unable to open Berkeley db /etc/sasldb2: No such file or directory
Sep 30 13:41:05 mailer postfix/smtpd[7577]: warning: SASL authentication problem: unable to open Berkeley db /etc/sasldb2: No such file or directory
Sep 30 13:41:05 mailer postfix/smtpd[7577]: warning: SASL authentication failure: no secret in database
Sep 30 13:41:05 mailer postfix/smtpd[7577]: warning: unknown[66.109.xxx.xxx]: SASL CRAM-MD5 authentication failed: authentication failure
I have saslauthd working fine for port 25. Here's the contents of /etc/postfix/sasl/smtpd.conf:
pwcheck_method: saslauthd
auxprop_plugin: sasldb
saslauthd_path: /var/run/saslauthd/mux
mech_list: PLAIN LOGIN CRAM-MD5 DIGEST-MD5
I thought I should copy this file into another in the same directory and call it submission.conf, but that doesn't seem to have done anything.
I've restarted saslauthd and postfix with no effect.
Here's my /etc/postfix/main.cf:

Ideally, I'd like saslauthd to work on both port 25 & 587. Can anyone give me some guidance as to how to accomplish this?
