SMTP and the routing restrictions confusion

I am confused at the difference between the relay settings that are needed
for my Exchange 5.5 server to send and receive SMTP from other SMTP servers
on the internet and the settings used for POP clients to send mail through
my Exchange server. (i.e. the Reroute incoming SMTP and the routing
restrictions) Seems like that should be a whole separate deal. I have
struggled with this for months and I'm still confused.
Can someone explain this to me please?

I'll have a go with that one.
Internet Mail Service inbound:
The DNS MX records will direct mail to you based on those records. You
will tell your IMS that you either need to route that mail to
"inbound" or route it to a specific destination. That destination will
typicall be internal. If this is specified, relaying will be allowed
for that destination domain.
IMS Outbound:
Your POP clients will connect via smtp for all mail. What you need to
do for them is to allow the IMS to relay mail for authenticated users,
but not for anonymous attempts (i.e. relayers/spammers who don't have
an NT account at your place)

It does seem a bit confusing at first but it's best not to get all
Faustian with it, keep your brain on a footballers level (shallow)

SMTP restrictions #2
A few questions: If I configure the "Limit Message Size(KB)" does this pertain to the attachments as well? Also, does it affect both inbound and outbound? If the "Limit Message Size" is exceeded by the attachment does the attachment get stripped and the message (body) go through? If nothing goes through, does the sender recieve an error? Sorry so many questions. Thanks! Message size is the sum of the headers, body and the attachment. There is no setting specifically for the attachment size. When there is a violation, the entire message is bounced back to the send...

Disclaimer using IMSEXT.DLL corrupting SMTP mail
I have installed IMSEXT.DLL and configured it to append a disclaimer to all outbound messages (article 258206). In order to work for our POP clients, I also set up the IMS to route all messages through the IS (article 238471). It works fine for messages originating from Outlook clients. Messages sent via SMTP from POP clients, or routed through the server via Custom Recipients get corrupted. Attachments (MIME) also get messed up. The simplest symptom to describe is that all text styling gets stripped. I haven't been able to find any more information on supporting non-Outlook client...

Exchange routing
Hi I am just evaluating the CRM1.2 and trying to understand a little about the Exchange connector. Does the exchange router only route messages with a guid in the subject line? If the client deletes this from the subject how do you get the response back into CRM? thanks Robert As mentioned, the CRM Exchange connector will route e-mails with the GUID in the subject line. You can also configure it to route inbound e-mails based on e-mail addresses as well. For example, you could set it up so that if sent you an e-mail, and Joe was an existing contact in the CRM, ...
