Hi,
I'm looking for input from people on how they handle attachments, and
people using email as a file transfer service. One of our users must have
posted to a job site recently, soliciting resumes from people
internationally. This resulted in 100+ emails from random people who had
never emailed this user before, many of which had no subject and no body,
just a PDF attachment. Some had the "Sent by my iPhone" signatures, but
that's about it. Virtually all of them were tagged as spam due to bayes.
Any recommendations? There wasn't otherwise anything wrong with the
attachments - they were all legitimate resumes from legitimate sources.
Should they be blocked? Should I retrain bayes to not consider these spam?
I'm now training bayes with them as ham, but it will take a lot to
offset these. Same with emails that only contain images. Should an email
with only an image attachment with no subject and no body but sent from a
legitimate source and otherwise not dangerous be considered spam?
Many also hit DCC, presumably because of the empty body. Is it possible to
train DCC with one of these to be ignored that would then apply to all
similar messages? I've generated a signature of an empty email before, but
unsure how much variation is allowed before it's no longer considered the
same signature.
Somewhat related, is the ExtractText plugin useful anymore? I had to
disable it altogether because of the money rules and people emailing their
credit card statements, and even though they talk about money, it's not
malicious.
