Postfix to relay through my ISPs SMTP with no tls problem


Hi all,

I revert once again to this forum as I am at a loss as to what is happening.

I am running Slackware 11.0 as a mailserver that runs Postfix v2.3.3 + Dovecot-IMAP v1.0rc14 + MySQL (for virtual domains & accounts) + Postfix Admin v2.1.0.

My mailserver as is, is working fine with authentication and TLS encryption for sending however due to that fact that my e-mail was all being marked as SPAM (since no reverse lookup on my domain was possible) I decided to use my ISP's SMTP server for relaying.

To accomplish this I added the following to /etc/postfix/main.cf:

FYI my ISP's SMTP server requires authentication with no TLS.

Code:
relayhost = [smtp.myisp.pt]
smtp_use_tls = no
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/smtp_auth
smtp_sasl_security_options = noanonymous
Then I edited smtp_auth to include my ISP SMTP server and ran postmap smtp_auth

However now every time I try to send mail I get the following error messages in /var/log/maillog:

Code:
Jan 16 20:18:52 cortex postfix/smtp[7751]: warning: unsupported SASL client implementation: cyrus
Jan 16 20:18:52 cortex postfix/smtp[7751]: fatal: SASL library initialization
Jan 16 20:18:53 cortex postfix/master[1434]: warning: process /usr/libexec/postfix/smtp pid 7751 exit status 1
Jan 16 20:18:53 cortex postfix/master[1434]: warning: /usr/libexec/postfix/smtp: bad command startup -- throttling
I have tried many different options in mainf.cf but I allways get the same error message. I also tried without the "noanonymous" but same thing happens.

As a reference I leave here my configuration files, any help would be much appreciated.

## postconf -n

Code:
alias_database = hash:/etc/mail/aliases
alias_maps = hash:/etc/mail/aliases

How did you compile postfix? Did you include support for Cyrus SASL? Post your makedefs.out.

Hi Berhanie,

Thanks for your reply.

I have been using (when I can) precompiled packages, for postfix I used the following: http://www.linuxpackages.net/pkg_details.php?id=9775 as you can see in the description it is compiled with cyrus-sasl support.

Yes, but it also says:
Quote:
This build supports TLS (needs openssl), MySQL (needs mysql) and SASL (needs cyrus-sasl-mysql).
Did you install the guy's cyrus-sasl-mysql package? (First, make sure you really need it, since I think Slackware 11 already comes with cyrus-sasl.)

Yes slackware 11 does come with cyrus-sasl, which I have tried. I also downloaded source and compiled with the following options:

Code:
./configure --prefix=/usr --sysconfdir=/etc --enable-anon --enable-plain --enable-digest --enable-cram --with-mysql=/usr/bin --with-saslauthd=/usr/sbin
However the problem persists.

Concerning the guy's cyrus-sasl-mysql package it is at: http://www.linuxpackages.net/pkg_details.php?id=7543 although it has been compiled for slack 10.2 I also tried it but I keep getting the same error.

Then, we have a problem. I suspect that postfix wasn't built with Cyrus SASL as advertised. Here's mine:
Code:
root@machine:~# postconf -A
cyrus
root@machine:~# ldd /usr/local/libexec/postfix/smtp
        libsasl2.so.2 => /usr/local/lib/libsasl2.so.2 (0x4002d000)
        ...
You can do a ldd as above for the final proof. Yours is probably in /usr/libexec rather than /usr/local/libexec.

Solved

Berhanie, firstly i'd like to thank you for all your help! It has been invaluable as to tracking down the problem which apparently was the package as you had stated.

I tried a different package http://www.linuxpackages.net/pkg_details.php?id=10281 and now everything is working perfectly.

Code:
#postconf -A
cyrus
Once again thanks!
