Hi there,

we experience problems with headers containing a FROM like this ...

From: =?utf-7?B?UHJvZi5gRHIuIFJ2ZGkgU3NobWllZGU=?= <user@mail.exampl

The newline in FROM should be okay regarding to RFCs.
The spam-status for those mails:

X-Spam-Status: No, score=4.259 tagged_above=2 required=6.2
        tests=[ALL_TRUSTED=-1, DKIM_ADSP_NXDOMAIN=0.8, FROM_ADDR_WS=2.999,
        HTML_MESSAGE=0.001, MIME_HTML_ONLY=1.105]

I tried to deactivate the "bad header check" in iRedAdmin-Pro for those users, to get rid of the score for FROM_ADDR_WS, but i didn't work. Spamassasin is inactive, and there is no setting for FROM_ADDR_WS in /etc/amavis.

Anyone an idea?

Thanks in advance


Re: Spam Score for FROM_ADDR_WS / bad header

you can set the score for FROM_ADDR_WS manually to 0 so it disables this check completly, this is not rladed to iredmail/amavis, its from spamasassin

Thanks for the reply, it seems spamassassin is not in use, but amavis seems to read out those settings. The spam score for FROM_ADDR_WS vanished now. My initial problem still exists, the sender gets a bounce message, my best guess is because of the newline in FROM.

What's the content of bounce message? It's useful for troubleshooting.
