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?
