I’m writing an app which allows users to send out a text-only email to a bunch of recipients. I want to try and generate the subject of this email from the body of the message, to avoid the need for a subject field
Is it safe enough to do this? Are these emails likely to fall foul of spam filters?
I’m already scanning the entire email for spam words, so there won’t be any in the subject
you could download the widely used spamfilter Spamassassin and search for ‘SUBJ’ in the *.cf files, this will give you many spamrules that trigger based on subject (like empty subject, all caps, bad words, bad encoding of non-ascii characters etc)
