Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I recently installed a postfix + dovecot + dkim multi domain, multi user, multi alias mail server on my debian squeeze system. Everything works except for one big issue that basically makes the whole thing useless:

Every single email sent by my server goes straight into spam. (gmail, hotmail)

First thing i did is doing the well known allaboutspam test and all is checked (green) except for the BATV thing (yellow):

Reverse dns: green
HELO Greeting: green
RBL: green
BATV: yellow
SPF: green
DKIM: green
URIBL: green
SPAMAssassin: green
Greylist: green

I'm really confused and i can't see a way to solve this issue. Ask me any detail if you need.

So, Gmail tells you:

Why is this message in Spam? It's similar to messages that have been detected by our spam filters.

This is generally a problem with spammy looking content.

And indeed, if I received a message containing "ciao bello ti invio il codice la prossima volta fammi sapere" I'd probably mark it as spam too. It's certainly spammy looking enough.

You can do two things:

  1. Rewrite your content to be more professional in nature.
  2. Click "Not Spam" a lot.

Did you setup reverse DNS properly? Make sure the forward and reverse records for your mail server match.
