Tue, 07 Feb 2012 19:41:08 +0000 http://www.zulius.com/wordpress/?p=3#comment-507 Thanks for the quick reply... everything is working now, what I ended up doing was purging postfix and reinstalling it, and choosing "no configuration" during install. I then added copied the default main.cf.debian to /etc/postfix/main.cf and added the lines you have in your setup. What's interesting is that when I used :80 on the smtp server, mail.log was showing the connections were refused, so I removed it and edited sasl_passwd and did the postmap thing again, and lo and behold, mail.log is now showing status=sent and I'm getting my test messages.

Tue, 07 Feb 2012 15:46:49 +0000 http://www.zulius.com/wordpress/?p=3#comment-505 I'm running Ubuntu Server 10.4.3 that hosts our in-house repair software and needs to relay messages from a php form to our isp's smtp server. Everything previously ran on a win2003 server and everything worked normally. I have smtp= set in php.ini and installed postfix, sasl2-bin, and ran through all the steps on your tutorial and still nothing goes through. I tried both with and without :80 after the smtp server specified in relayhost. When I check /var/log/mail.log, I'm getting server postfix/smtp[...]: fatal: open database /etc/postfix/sasl_passwd.db: No such file or directory. Help! I'm no linux expert, but I'm learning on the fly :/ I'm running Ubuntu Server 10.4.3 that hosts our in-house repair software and needs to relay messages from a php form to our isp's smtp server.

I spent several days looking for answer why my clearos postfix can't authenticate with ISP's smtp server. Ed found this: <blockquote> I think I figured out my solution: postfix seems to insist on applying the Cisco PIX workaround. I added this line in main.cf: smtp_pix_workarounds = So now the smtp server is recognized as ESMTP and EHLO is used by default. Email started flowing! </blockquote> Thanks, with all my hart @Ed, Tim

But almost! first try your post resulted in success for me. I must reinforce your kindly and carefully noted Troubleshooting entry RE: (Authentication failed: cannot SASL authenticate to server ...: no mechanism available) and the fix given, FIX: smtp_sasl_security_options = noanonymous You see in my ubuntu setup the default was smtp_sasl_security_options = noplaintext, noanonymous Looks good? Result was the exact error you point out. Had the drop the noplaintext part and right away mail sent error free. NICE!! thank you! Also so others won't sweat like I did when the check for libssl failed, this set up works fine. Of course, that could be because I use the Courier Delivery Agent instead of cyrus. Note: smtp_sasl_type = cyrus on this machine. I thought that would not work. I did not install cyrus. For courier install I followed http://flurdy.com/docs/postfix/ GMail, ubuntu 11.10, Courier (not cyrus)

I didn't know of the [host] trick, but I simply made a MX record on a unused subdomain. Note: Debian Lenny's SSL crt file is /etc/ssl/certs/ca-certificates.crt.
