sendmail, messages bouncing, Domain of sender address does not exist

I have a problem that just started since installing a Sonicwall firewall, although I don't see how that would affect this problem. Possibly coincidence.

I'm sending message from a server on our office LAN. They are failing with the following message:
   ----- The following addresses had permanent fatal errors -----
    (reason: 553 5.1.8 <hprsportal@webserver.hprs.local>... Domain of sender address portal@webserver.hprs.local does not exist)
The address shown is the local LAN address of this server. The public address is In my file I have:
dnl FEATURE(`masquerade_envelope')
dnl FEATURE(`masquerade_entire_domain')
The webserver host is sending via a local SMART_HOST relay. I have all the masquerades turned on.

Why is it going out with webserver.hprs.local and not simply or even

Doh! I see now that I have dnl ahead of the masquerade statments! I've removed that and will monitor the emails to see if they're going through now.

I don't know why I commented those lines out in the first place. I didn't make a comment about it. I guess I find out why the hard way.

Later ...

Yup, uncommenting the masquerades seems to have fixed the problem.
