Question SMTP SASL authentication


I'm running postfix on FC14. Followed Falko's brilliant-as-always guide to do this. I setup 3 virtual users. I'll call them a@domain, b@domain, c@domain. I inserted them into the user table in that order, and used ENCRYPT command on the password field for all.

I am using my cellphone to connect to the accounts. My phone managed to connect to both incoming (IMAP) and outgoing (SMTP, duh!) servers with a@domain's credentials.

However, for b and c, it only authenticated the incoming, but responds saying User Authentication failed for outgoing. If I put a's credentials for outgoing, it works.

This is also true in Thunderbird. I have to use a's credentials to login to SMTP.
Maillog shows the following:

Using b
Mar 22 23:44:21 server postfix/smtpd[6560]: warning: unknown[]: SASL LOGIN authentication failed: authentication failure
Using a

Since a's credentials work, it would only follow that b and c should work, too; I can't see where there would be a config issue... what could be the problem?
