Re: SMTP Firewall

[Kenneth_W_Fox () sbphrd com]

There are a number of reasons for and against. Depends on the firewall your
using and the volume of traffic. WHat percentage of your firewall's
resources are currently being expended on email (smtp) in & out. Or perhaps
they want a specific piece of firewall softwware that does something your
current firewall's software doesn't. Depends what other services are being
pushed through your firewall (nntp, real audio or video, http). Look at it
this way - if you already have more than one firewall, you should probably
put http through one & smtp through the other. I look at having an array
(2+ firewalls) all configured identically but with the non-primary services
turned off on each firewall. then if there's a problem with one the others
back it up in short order after your manual intervention - simple level
redundancy.
