Betreff: [Assp-test] Block URL only emails with special message?
We're seeing more and more aol and yahoo accounts that are whitelisted get
hacked. Then we see email messages with only a url in them that get
through
our filters.
We could easily create a strict bomb that rejects emails with only URL's
in
them. The problem with that is that our users get legitimate emails from
time to time with only a URL and we wouldn't want them rejected. These
URL's aren't in the URIBL.
I was thinking of some way of rejecting messages with a different error
message, maybe something like "Messages only with URL's are prohibited.
Please resend your email with more information" or something like that.
This would need to be implemented though.
Any other thoughts of how to use existing v2 functionality to handle this?
Thanks
