[Dovecot] Using Dovecot SASL with postfix
I'm trying to use Dovecot SASL with postfix 2.3.3 and when trying to send mail I get the debug output below. I don't know enough about whats going on to know where the problem is but something clearly is not right. I would send the configurations for postfix and dovecot except they are clearly talking to each other so I kinda doubt its a configuration issue. The machine can afford to be down for an hour or two at a time for testing stuff if needed.

A working auth looks like this, I'm thinking that IMAP versus SMTP should not be *too* big a difference in this case.

Invalid input? Maybe a broken client? What's the client? You mentioned the Postfix version, but not Dovecot. There were some problems with SASL PLAIN AUTH in the 1.0-beta series.
Hmmm, PLAIN AUTH should be a uuencoded "username\0username\0password" string. Your client just sent "jonathan"?

There you have it. "SASL PLAIN authentication failed".
All I can say is that a literal copy-and-paste from the Postfix SASL_README works for me, and it has been working for a long time. I was using Dovecot SASL with the 2.2 patch, and a modified version thereof in pre-20051221 snapshots of Postfix 2.3. (The syntax was slightly different for the 2.2 patch.)

I'm using VersaMail for the palm treo 650, and being pretty sure it was the client now, dug into google and found someone with the same issue. I'm now 99% sure that the problem lies with versamail rather than postfix or dovecot. Apparently PLAIN auth does not work but LOGIN does work correctly. OT can someone point me to a comparison/summary of LOGIN versus PLAIN and whether I would be able to disable plain without causing too many issues with other clients? I did put a support request in with palm so hopefully it will get fixed (ha ha :P)
Thanks, Jonathan
