Postfix + Cyrus-SASL
 
Hello! I've got Postfix with Cyrus-SASL (from packages) on Debian Lenny. When I'm sending mail through TLS on the Postfix everything is good. Problem is when I want to send mail through SSL. This is what I have when I'm trying connect by telnet:
Code:

root@borekfalecki:/home/seprob# telnet localhost 465
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
220 borekfalecki.pl
ehlo me
250-borekfalecki.pl
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-STARTTLS
250-AUTH LOGIN PLAIN
250-AUTH=LOGIN PLAIN
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN
auth plain [pass]
535 5.7.8 Error: authentication failed: generic failure

In logs I have this message:
Code:

Nov  9 19:08:21 borekfalecki postfix/smtpd[16130]: warning: SASL authentication failure: cannot connect to saslauthd server: No such file or directory

Nov  9 19:08:27 borekfalecki postfix/smtpd[16130]: disconnect from localhost.localdomain[127.0.0.1]

Postfix is in the chroot. I launch Cyrus-SASL by command which says its that its place is in /var/spool/postfix/var/run/saslauthd. I checked and I saw that it creates files there.

This is what I have when I want to send e-mail through Thunderbird:
Code:

Postfix is not able to find the saslauthd socket, try setting it with smtpd_sasl_path

seprob 11-17-2009 03:33 AM

I tried to set "smtpd_sasl_path = /etc/postfix/sasl" then "smtpd_sasl_path = /etc/postfix/sasl:/usr/lib/sasl2" and then "smtpd_sasl_path = /var/spool/postfix/var/run/saslauthd". Nothing works.

I read this. Everything is set according to this article. I've got still same messages in logs.

seprob 11-18-2009 08:12 AM

OK, it works. I changed in "/etc/postfix/master.cf" that SMTPS should be run in chroot. But I only can connect through Telnet. I can't connect by Tunderbird. I've got in logs following message:

Nov 18 15:12:00 borekfalecki postfix/smtpd[11826]: timeout after UNKNOWN from czapla.IOd.krakow.pl[149.156.29.2]
