Hi, I've been using ISPConfig for a while, and i must say it's really neat and a clean/ordened controlpanel! But my problem, i've added clients in ISPConfig with some sites. When the client sends an test email to a gmail address or a hotmail address the email is marked as SPAM (in gmail) and is never delivered (in hotmail). recently added the SPF record, but it still dont work, in the header i can see that the SPF result is passed, so that's a good thing. I will include the header file from the SPAM marked email that I found in the SPAMbox of gmail: My quess at this moment is the Message-ID which ends with @localhost, or maybe the return-path with [email protected] in it. Does anyone knows where the problems are? Because this problem is very irritating me. Thx in advance.
