Looking for some advice, hope it's OK to ask here. I have a few
customers over the past several months start getting an unusual amount
of messages being blocked or returned when sending via our SMTP servers.
I have checked that none of our servers are listed on any databases, but
after some querying of the customers involved, I have found that they
all have recently been sending mailing to their customer lists. Even
though all of them assure me that these lists are only of the opt-in
variety, it is the only thing they all have in common and seems to be
the problem.
I have also noticed that every time one of these mailings is sent with
several AOL users, our servers will be temporarily blocked. Are there
some precautions I should take to possible get their mails trusted? Any
other advice?
I would likely look at setting up feedback loops for Spam complaints
