    Dear Ladies and Gentlemen,

    I am writing to seek some advice about adding disclaimers to outgoing
    mail in this situation,

    ISP ------ FreeBSD/Sendmail-----Lotus Notes
               4.9 /8.12
     
    All mail transits the FreeBSD instance where it either is

    1 delivered 'locally' by dealiasing to Foo@Notes, in the case of
    incoming mail

    2 forwarded subject to the mailertable entries (for some direct delivery
    of incoming mail to FreeBSD boxes, otherwise forwarding to the provider
    MTA). This is the case for _most_ outgoing mail and some incoming.

    This setup provides performance and control (eg multiple aliases,
    queues, web management of aliases) that doesn't exist in the MS/Notes
    space.

    (Please, no low jokes about 'Notes. We accept that the best thing about
    it is that it is not Exchange and accordingly we have been very happy
    not to have become the victim of so many MS vectored virii.
    Unfortunately, such is the pressure for 'integrated' products that
    Exchange may be on the way)

    My employer wants to add disclaimers to outgoing mail and therefore I
    would like them added by the FreeBSD instance (to avoid mail to Request
    Tracker etc being polluted with disclaimers) rather than by 'Notes.

    It seems to me, however, that milters do not allow filtering based on
    direction of flow (or recipient ne 'internal domain'), so I would be
    very grateful to hear some suggestions or descriptions of how folks add
    disclaimers for outgoing mail only.

    Perhaps two sendmail instances is a possibility ?

    We are not committed to either the MTA or the design above. We seek a
    robust, manageable (ie FreeBSD) solution that can be implemented with as
    little butchery as possible, to either replace or complement the
    FreeBSD environment above.

    The approach we seek is proven software; we may be able to tap the mail
    stream with divert sockets, but quite simply do not have the coding
    skills to produce a robost result.

    Thank you,

    Yours sincerely.
