Hi I've configured my server like said in this guide http://www.howtoforge.com/perfect-server-debian-squeeze-with-bind-and-dovecot-ispconfig-3 but php scripts dont send emails... What do you think could be the problem?
If your server is setup at home, it's likely that your ISP is blocking your email. There are many threads related to this...
Thanks for your reply but I found the problem, it was amavis that was stopped ( I had stopped it during my tests to free some ram )
