Tárgy: [EXIM] 1 incoming/1 outgoing considered more safe ?

Good day,

    We've just started an email project at work and a comment that
    came from out internet connector (I don't know whether provider is
    quite the correct way to put it in our case) is that having a
    seperate incoming and a separate outgoing SMTP server is better
    security wise.


    Now is this a very sendmail centric problem or would you consider
    this a wise idea no matter what ? Thinking in terms of how exim
    can work, with one daemon listening on port 25 and a cron job
    running exim every so often to send out messages or having exim
    run a seperate runner process using -q, this problem may be
    completely irrelevant to exim, but having used smail and then exim
    for the last cuople of years I cannot say what the differences are
    between sendmail and exim, and exactly what problems could occur
    with a combined incoming/outgoing server ?


    Could anyone hazard a guess at this - have there been problems
    with sendmail in the past which have required splitting, problems
    that don't affect exim ?



Thank you for any help,

Sincerely,

Adrian Phillips

PS. Offtopic - does anyone have experience with M$ Exchange or
Netscape Message Center that would be willing (in private email) to
let me know of any problems (giving me ammunition against using them
:-)
