A strong word of caution again Praveen - in my experience,
EXCEPTION case handling require more administration and are
difficult to hand over to second level support.  If you intend
to be 'one-deep' for support, or the only one providing the 
support you stand a better chance of accurate administration of the
exceptions - however; even you may forget the exceptions from 
time to time.

We do offer users two mail accounts, one for internal and one
for external.  This required alteration in the directory
synchronization process; the internal address was sent to the
mail systems focused on internal communication, and the external
address is provided via RFC822 addressing in X.500.  Presenting
two accounts to the world is confusing.  

Additonally, a user may think that they prefer two accounts, until
they forget to check one and find that they have missed a very
important meeting.  I recommend users to stay with one account.

In a 'perfect' world, each organization would have only one source
for e-mail provision anyway.  [SOAP BOX! PERSONAL OPINION!]
