Hi, I'm know to postfix, and I am experimenting some problems trying to configure a SMTP relay on my server using Postfix. I am using Ubuntu 10.04 and I have installed sasl and postfix, using the tutorial here : https://help.ubuntu.com/community/Postfix. I use my ISP (1and1) to send the mail. When I try to send one using sendmail, I get the following error (using postqueue) : (SASL authentication failed; server auth.smtp.1and1.fr[212.227.15.168] said: 535 Authentication failure) The logs in /var/log/mail.log shows a problem with the certificate verification, and I have no clue where this certificate is coming from, since I have created one (as specified in the tutorial) Feb 21 17:59:46 scarlatti postfix/master[12295]: terminating on signal 15 Feb 21 17:59:47 scarlatti postfix/master[12531]: daemon started -- version 2.7.0, configuration /etc/postfix Feb 21 18:01:38 scarlatti postfix/master[1279]: daemon started -- version 2.7.0, configuration /etc/postfix Feb 21 18:04:00 scarlatti postfix/pickup[1320]: 7C1F385624: uid=1000 from=<xxxx> Feb 21 18:04:00 scarlatti postfix/cleanup[1659]: 7C1F385624: message-id=<20110221170400.7C1F385624@xxxx> Feb 21 18:04:00 scarlatti postfix/qmgr[1321]: 7C1F385624: from=<xxxx@xxxx>, size=312, nrcpt=1 (queue active) Feb 21 18:04:01 scarlatti postfix/smtp[1662]: certificate verification failed for auth.smtp.1and1.fr[212.227.15.184]:587: untrusted issuer /C=ZA/ST=Western Cape/L=Cape Town/O=Thawte Consulting cc/OU=Certification Services Division/CN=Thawte Premium Server CA/[email protected] Feb 21 18:04:01 scarlatti postfix/smtp[1662]: 7C1F385624: SASL authentication failed; server auth.smtp.1and1.fr[212.227.15.184] said: 535 Authentication failure Here is my main.cf : # See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name.

Hi Falko, Thanks four your message and pointed me this tutorial. I have remove my previous installation (including directories /etc/postfix and /var/spool/postfix) and installed everything from scratch, using : To install postfix : https://help.ubuntu.com/community/Postfix And then to configure it : http://www.howtoforge.com/postfix_relaying_through_another_mailserver And it worked fine from the first mail. Thanks, Mathieu
