who can I enable to send mails from the web hosting server? atm the mailing (postfix) is disabled. (and i don't want to interfer the mailserver)
You need to have in both server (web and mail) an MTA installed (postfix in this case). Here you can see the setting you have to set in both servers. (mail server must be a relay server only for your web server) http://www.howtoforge.com/forums/showthread.php?t=52362 Regards
thanks for your help i did the following apt-get remove postfix --purge apt-get install postfix (without the mysql stuff) and it run out of the box. (its not relayed threw the mailserver but thats in my case desired) thanks for your help!!!
It works out of the box? be carefull, maybe you mailserver is acting as an open relay for the world, and you MUST limit to only act as relay for the servers you want.
thanks for warning no i meant the webserver itself is able to send messages now under his own hostname, not relaying!
But a misconfigured postfix may lead to your server beeing an open relay, no matter what local services are able to do. More information, tools & links you may find e.g. here: http://spamlinks.net/prevent-secure-relay-test.htm
thanks for that link i didnt know it really good! since no smtp is opened, and i only use to send mail.. http://verify.abuse.net/cgi-bin/relaytest: All tests performed, no relays accepted.
