I followed this guide for setting up ISPconfig 3 http://www.howtoforge.com/perfect-server-centos-5.3-x86_64-ispconfig-3 all is working fine, but when i wanted to work with e-mail i run into a problem. Webmail interface is working fine, but after sending mail, it goes to the sent-mail box, but nothing is ever delivered. I the mail que i find hundreds of entries like this: Code: -Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient------- 7A2D4541DE 766 Thu Jul 9 19:03:02 root [email protected][email protected][email protected] [email protected] shows in the real log my private e-mail, i used for testing. Mail log is completly empty Mail-warn log is empty. I have no clue about what is wrong, or where to start looking, i'v searched over the internet, but most problems with mail show errors in the maillog file. It seems nothing is happening. The services are started correctly, and with update script refreshed.
