Good morning.

I'm having some trouble with a sender (who is whitelisted globally and also per-recipient) who gets its email always "Quarantined". This sender always obtains a spam score near 100 (mailbox on gmail.com).

These emails are in txt format and has attached an xls and a pdf files: Nor XLS or PDF are banned extensions in my amavisd configuration but these emails are always blocked as "Banned" in iRedMail Pro panel.

Any suggestions?

Re: Banned emails.

You can update Amavisd config file to allow 'XLS/PDF' attachment.

Could you please show me the mail header of this quarantined email? I just need the headers which have names start with 'X-Spam-'.

Re: Banned emails.

Adding something like this to amavis.conf?

$banned_filename_re = new_RE(
[...]
existing rules
[...]
    [qr'.\.(pdf|xls)$'i => 0],    # <-- '0': allow
);

I'll send you the header tomorrow!
Thank you.

Re: Banned emails.

Ok, today we have no banned emails from that user so modify amavis.conf "server wide" did the trick.

Its spam score is always "-98.253" but its emails was no longer banned. Today I notice that also ".doc" files were banned... Ok, I can add it to the previous exclusion but it is the expected behaviour? I didn't explicit ban that extensions...

Re: Banned emails.

You can add .doc as allowed file extension like you already did.

Re: Banned emails.

Banned file extensions are listed in Amavisd setting '$banned_filename_re'.
