Hi, I have a small problem to which I do not have a clue. I am having a linux router which has a public IP and have hosted a few websites from computers which are on lan. The scenario is like this Code: router---> www.myserver.com internal LAN ip 192.168.0.1 domu1----->www.myserver.com/domu1 on internal LAN 192.168.0.11 domu2----->www.myserver.com/domu2 on internal LAN 192.168.0.12 domu3----->www.myserver.com/domu3 on internal LAN 192.168.0.13 domu4----->www.myserver.com/domu4 on internal LAN 192.168.0.14 Now the sites www.myserver.com/domu1 to domu4 all have registration pages. I have drupal as web development platform.These sites can be accessed on internet with only home pages. When a user tries to create a new account on any of them say for example www.myserver.com/domu1 the outgoing registration email is not going. What steps should I do to check it ? How can it be made possible? To my mind it comes I should setup SMTP and do some forwarding routing with ports etc but I am not sure so need suggestions. I googled about SMTP configuration and came across that Drupal does not seems to have good SMTP configuration http://ubuntuforums.org/archive/index.php/t-855064.html
Do you have a dynamic IP address? Then you're most likely blacklisted, and you should set up relaying: http://www.howtoforge.com/postfix_relaying_through_another_mailserver You can check if you're blacklisted: http://mxtoolbox.com/blacklists.aspx
