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:

Code:

  ----- The following addresses had permanent fatal errors -----

<jfdadsf@att.net>

    (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 webserver.ohprs.org. In my sendmail.cf file I have:

Code:

define(`SMART_HOST',`mail.hprs.local')dnl

dnl MASQUERADE_AS(`ohprs.org')

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 ohprs.org or even webserver.ohprs.org?

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.
