Your original mail had 2 "MASQUERADE_AS" lines. I believe that you don't
want that. only one.
as for your most recent question, to quote or not to quote, I believe either
is acceptable. the quotes (single open, and single close) prevent expansion.
Otherwise, any wildcard characters in the text string might get expanded.
(ref: /usr/share/sendmail-cf/README)
and as originally noted, you probably do NOT want a trailing dot in any of your
MASQUERADE lines.
finally, the MASQUERADE_DOMAIN is used to map one domain (the listed domain in
MASQUERADE_DOMAIN) to another domain (the listed MASQUERADE_AS one, which is
why you do NOT want more than one MASQUERADE_AS line!)
it's not clear whether using MASQUERADE_AS *along with* MASQUERADE_DOMAIN will
map the local domain ALONG WITH the specified domain (i.e. the MASQUERADE_AS
domain) or not. (You might be getting bit here if it does not!). i.e. you are
showing BOTH
MASQUERADE_AS(`bigcorp.com')
and
MASQUERADE_DOMAIN(`bigcorp.com')
That almost certainly is NOT what you want. i.e. you want something like this:
MASQUERADE_AS(`<your external domain name>')
and
MASQUERADE_DOMAIN(`<your internal DIFFERENT from external domain name>')
If you have several internal domain names to masquerade, (or some that you do
NOT want to masquerade!) that is all covered in /usr/share/sendmail-cf/README!
The noted README file has quite a bit of information on the various sendmail.mc
options. You might want to search for MASQUERADE and review the various
sections.
Hope that is helpful,
-Greg

You can release software that's good, software that's inexpensive, or
software that's available on time. You can usually release software
that has 2 of these 3 attributes -- but not all 3.
