    =======

    I have an interesting issue with zonealarm.

    I am using the latest update to the free version.

    In the firewall settings, I have set it to allow "smtp.comcast.net" as a
    trusted site, obviously for the sending of email. The problem is that
    comcast has "smtp.comcast.net" resolve to a group of servers, presumably
    for rudundancey or load sharing. If I edit the comcast mail entry in
    the firewall, I can tell ZA to look up the current IP's, store them, and
    mail sending works. However, comcast periodically changes the servers.
    I sometimes have to edit the "Comcast Mail" lineitem in the firewall
    several times a day, sometimes it will work for a week.

    Shouldn't I be able to tell ZA to allow connections to
    "smtp.comcast.net" and have it work? Anyone know of a work aroud?

    Further info:

    I use Thunderbird for mail and news. Outgoing messages are virus
    checked by Kaspersky. Both Kaspersky and Thunderbird are in program
    control as "allowed to connect to the internet"

    Any thoughts?

    TIA

    OR weak attempts to get around blocklisting. You're talking about one
    of the biggest spam-sewers on the planet, totally unrepentant, and thus
    widely blocked by huge numbers of users, ISP and such, around the
    world. If you want unrestricted use of email comcast cannot sell it to
    you because they refuse to get rid of their huge load of spammers, and
    so they are heavily blocked by everyone who knows how. Just FYI.

    Again, probly trying to avoid blocklisting while keeping their spammers.

    Not that it directly answers your questions, but you could probably
    benefit from my method of dealing with mail.

    Procedurally, you are correct. This implies that DNS lookup is also
    allowed (ie: port 53).

    If you allow ALL port 53 access and control domain access, then you
    should be fine
