Hi;
Interesting
trend... I keep seeing spam coming from strange userID's (randomly
made)@Durability.com and other domains we host for several
charities.
I think that
solves a couple of problems for these people - like the MX record exists and
also chances are that a company might have Whitelisted their own
domain.
Could this be a
possible test? A list that we can create of legitimate eMails from a
domain and if a sender is from any of these domains then the UserID has to
match!? or is there a way this can be tested directly with IMail so if a
user does not exist from a domain then the eMail is not accepted from that TO
address?
Naturally for this
to happen the domain has to first exist in IMail and then the
user.
Regards,
Kami
