I'm pondering adding a spam category to std_reason in
Mail::DeliveryStatus::BounceParser.
This would record when a message was bounced because the recipient
considered it spam.
Does this sound reasonable?
Yes.
I think there had been some talk about this a long while back, when I
was using MBP for a project working on this a little more actively.
The only issue to me is that calling it spam doesn't make it super
obvious whether the message itself is spam (i.e., not a bounce at all,
but spam), or whether the bounce parser thinks that the message was
rejected because the intended recipient considered it spam (I think it
might actually be useful to have a spam classification for messages
tagged as spam by an external filter, but passed along to the
bounce-parser).
It's a potential problem, with the name spam, although if they read the
documentation they'll see it explains what's considered spam (see my tree on
github).
On a more technical level, I think it may be difficult to do this
reliably. Presumably, dnsbl based rejections (e.g., 554 10.0.0.1 blocked
by
dnsbl.example.com), anything containing the word spam (554 message
appears to be spam), and other low hanging fruit would be easy
enough to match, but I think any such logic should definitely err on the
side of caution. Plenty of policy based rejections aren't due to spam.
At the moment the classifications I've done are only on fairly obvious you
have been blackllisted / are considered spam examples, so hopefully we're
okay here.
I don't have as much time to spend looking at bounces as I have had in the
past few weeks, but I still hope to keep tweaking things on and off.
