Email server (Exchange) behind an ASA

    I am a contractor, and install multiple PIX\ASA over the last couple
    of years. Most of my clients are small businesses, and they have
    their email server in house and we forward SMTP to it. I know in the
    PIX setups, to remove the default command fixup protocol smtp 25, and
    I just learned to remove the class inspection on the ASA for inspect
    esmtp. I am wondering if there are any more commands that I need to
    add or remove to assist them. The issues they experience range from
    not being able to send or delayed sending to some users having their
    PDF's stripped (a really odd one, and we contacted Cisco and they said
    everything was setup correctly). Removing the class inspection has
    helped for most things but not all.

    Normally you remove the esmtp inspect and adjust the dns mtu. What does a
    "show service-policy" tell you?
