    My situation:

    I send bulk mail via a VPS hosting.
    I send about 30 thousand mails a day, 1400/hour divided in 2 "phplist" engines running in 2 different ips from the same VPS.

    In fact, my mail lists are of bad quality and I receive a large amount of bounces, so I believe that from the 30 thousand I send very few reach a person.
    Anyway, I still receive a nice feedback from my mailing, and I'm very interested in tracking bounces to make my lists better.

    My question:

    Many of the bounces I receive are because of lacking a Reverse-DNS. I asked sometimes for my hosting to put a reverse dns for me. They put, but misteriously the reverse dns configuration disappears after some time. I've heard once that using reverse dns and sending s-p-am is not good, because many good mail clients which flag spam only accepts mails with reverse dns... So, using it, would make the chances of being flagged higher. Does it makes sense?

    At the same time, with no reverse dns, I receive a too high number of bounces. I'm not sure if my VPS provider knows that I send s-p-am, and intentionally removes my reverse dns from time to time, or if it's just a bug that makes it out.

    One of my ip is flagged in about 4 spam lists.
    The other one is only flagged in one.

    In resume,

    What would you recommend for sending s-p-am? Having a reverse-dns or not?

    Also, an additional question, does it worth sending spam for "hotmail" and "yahoo" mails knowing that it will fall on the "SPAM" box?

    I'm a little afraid of " AT gmail" mails that have that "S-P-AM" button for

    the person to click. Does it worth removing AT gmail from the lists?
