While
the PIX has some of its own problems, I am fully aware of them and know how to
get around them. I call it "no fixup protocol smtp", that resolves all
email related problems on the PIX.
Linux??? Puh-lease! What do you think this piece of sheit WG
is based upon? As for how "secure" it isn't... Shall I hack it now
or later?

Subject: RE: Removing Unknown SMTP/ESMTP Message Headers/Keywordsso I take you were not happy with your Watchguard box ;) Maybe you should look at setting up a Linux firewall. Then you can modify it to your heart's content.I understand that PIX has it's own set of idiosyncrasies when related to email.List Charter and FAQ at:-----Original Message-----

Subject: RE: Removing Unknown SMTP/ESMTP Message Headers/KeywordsI have a theory on Watchguard firewalls. They SUCK! SUCK! SUCK!! SUCK I say! SUCK!I have gone to using the Filtered SMTP service for now instead of the Proxied SMTP service. You will notice other email problems down the road as well when using the SMTP proxy. Such as other internet providers being unable to send you mail. This is because the stupid a$$ SMTP proxy transforms the mail from 8bit to 7bit among other things.My new PIX's have arrived and I can't wait to get them into production and toss these POS Red boxes in the trash.Just my $.02 mind you, but the WG FW SUCKS!!!DList Charter and FAQ at:-----Original Message-----

Subject: Removing Unknown SMTP/ESMTP Message Headers/KeywordsWe use a watchguard firewall which, by default, removes all unkown SMTP headers and ESMTP keywords. The following is a list of 41 headers and keywords that have been rejected by our firewall during the past week. I am considering adding some of these to the firewall's list of known headers/keywords. I'm especially interested in the security ramifications of adding these (we use Exchange 2000). Does anyone know of a specific reason To/Not To add these?.+- @A> 0 z[lpjo/Z\zm
