Hi there.

We have a policy where internal resources in GW have underscores instead of
spaces. For example:
which has an external email address: chief_bottle_washer@domain.com

Now, we'd prefer an external address of:

Currently we set up aliases on our external SMTP gateway. But I'd like to
have the address available from GW itself, especially so that the GWIA LDAP
server will respond to it.

I've tried the preferred email ID field and the nickname setting - but

of doing this? Does it have to be the SMTP aliases?
