* Danilo Godec <[email protected]>:
apparently, our users are receiving emails containing links and /or
references to various publications, some of which are considered
'predatory'. Emails usually contain ISSN (International Standard Serial
Number) and the idea is to scan the body of an email for the ISSN and if it
matches one on the 'blacklist', the subject of the email should be prepended
with some specific warning (other than ***SPAM***).
We're already using Amavisd-new on our inbound SMTP server, so I wonder if
that would be possible with it?

it is not possible as of now. Your best guess is probably to look for other
MILTER applications that let you scan a messages body and trigger an action,
such as changing the Subject:-header.
I was tinking if this could be solved using clamav with YARA rule that would
detect such ISSN and report it, probably with virus_name_to_spam_score_maps
?
