Welcome Banner

how do I change the welcome banner in exchange 2003?

As of now, it is reading "220 SMTP Service Ready" and I believe it is causing problems with emails going out and being returne undeliverable.

I have already tried that and when I telnet in, I still get the same banner.

Do you get the same banner if you do

 telnet localhost 25

from the server itself?  Your '220 SMTP Service Ready' banner is not the default MS Exchange one - I would guess that you have a firewall somewhere that can be configured to obscure the real text.

I did the "telnet localhost 25" and it comes up with the correct banner but when I run a dns report on www.dnsstuff.com, I get:

WARNING: One or more of your mailservers is claiming to be a host other than what it really is (the SMTP greeting should be a 3-digit code, followed by a space or a dash, then the host name). If your mailserver sends out E-mail using this domain in its EHLO or HELO, your E-mail might get blocked by anti-spam software. This is also a technical violation of RFC821 4.3 (and RFC2821 4.3.1). Note that the hostname given in the SMTP greeting should have an A record pointing back to the same server. Note that this one test may use a cached DNS record.

MAIL.portkinsale.com claims to be invalid hostname 'SMTP':
   220 SMTP service ready

I think DNSStuff is just complaining because the banner contains no host name at all.  I would see if your firewall can be congured to hide it.

I've seen this before with various firewalls.

You need to find out what the MX record really points to. Does it point to an external address that routes through a firewall like ISA or PIX, etc? One of these firewalls might be changing your SMTP banner.

220 SMTP Service Ready is normally watchguard firewall, i have also seen others like surfcontrol who run an SMTP Proxy engine within their firewall system.

Get in touch with your firewall vendor and have them disable "smtp proxy" feature on the firewall which is hosting your public IP.
