Postfix SMTP-AUTH Issue - Solved! I followed the tutorial called “Virtual Users And Domains With Postfix, Courier And MySQL (Fedora Core 5)”. I did it on Fedora 8. Everything went fine, with one or two minor issues that I solve quickly; except one annoying problem that I have no idea how to solve it. The problem is that only the first account ever created, for each virtual e-mail domain, is capable of using the SMTP-AUTH feature, the next added account keeps asking for password, and the “maillog” shows: Code: -May 9 11:12:28 punk postfix/smtpd[29706]: warning: unknown[192.168.111.254]: SASL LOGIN authentication failed “(Obs: The password is correct, I’ve checked that, in IMAP, for example)” -May 9 11:12:28 punk postfix/smtpd[29706]: lost connection after AUTH from unknown[192.168.111.254] In "messages" log file: Code: May 9 17:00:31 punk saslauthd[2497]: do_auth : auth failure: [user=<username>(without realm)] [service=smtp] [realm=<realmname>] [mech=pam] [reason=PAM auth error] With “My Outgoing server (SMTP) requires authentication” (@ Outlook) turned off, the sending is automatically rejected, as expected. With all the first accounts ever created, per domain, everything works fine (with internal and external delivers). EDIT: Only the first account ever added works. The others, with no visible reason, where using the username/password of that account for smtp-auth, when sending e-mails. They dont work with their credentials. Does Postfix/SMTP-AUTH has some kind of "Max Connections" per IP protection? Thanks in Advance!
That's the first time I hear of such a problem. Have you compared your configuration with the one from the tutorial to rule out typos?
Hello Falko, thanks for your time. I did what you told and i found the following error on configuration: in /usr/lib/sasl2/smtpd.conf Code: pwcheck_method: authdaemond log_level: 3 mech_list: PLAIN LOGIN authdaemond_path:/var/spool/authdaemon/socket i forgot to change the pwcheck_method, so i did it and switched it to "authdaemon" Now i cannot send from any account (but i do receive very well, using IMAP), and i got the following error message: Code: postfix/smtpd[20338]: warning: SASL authentication problem: unknown password verifier postfix/smtpd[20338]: warning: unknown[192.168.111.119]: SASL LOGIN authentication failed postfix/smtpd[20338]: lost connection after AUTH from unknown[192.168.111.119] Any help would be appreciated!
Solved! Solved! It was a simple problem after all! I had to restart "Postfix" and "saslauth" in the following order /etc/init.d/postfix stop /etc/init.d/saslauth restart /etc/init.d/postfix start
