The FAQ tip at http://www.sendmail.org/faq/section3#3.29 seems to rely
on the fact that the following entry in virtusertable:
@domain.com user+%1
will cause $1 in the .procmailrc config, e.g.:
ENV_TO=$1
to have the value "NNN" if mail being routed was addressed to
N...@domain.com.
what if instead of "NNN" I wanted to send the value "N...@domain.com"
to procmail?
@domain.com user+%1...@domain.com
will cause a too much recursion error,
@domain.com user+%1\@domain.com
seems to escape the ampersand, but rather than "N...@domain.com",
procmail will get "NNN\@domain.com". How does one get virtusertable
to send an ampersand without the escape character?
Or alternatively, how does one get procmail to remove the backslash?

Take a look at " Another possible _solution_ ..." link at the end of 3.29.
[ http://anfi.homeunix.org/sendmail/sharedmailbox.html ]
It should allow you to pass full envelope recipient address to procmail.
It is based on procmail script in /etc/procmailrcs/

From reading your anfi page, I didn't know you could put "!" on the

right side of a virtusertable entry to = the same thing as the left
side. I have been writing them in long form like mc/README mention.
Like:
us...@example.com user%3...@example.com
when I could have been using:
us...@example.com !

AFAIR Claus (?) stated sendmail.org position something like:
1) "!" handling in virtusertable reply should be treated as
"an undocumented feature" [It _MAY_ change without a notice]
2) Also undocumented _VIRTUSER_STOP_ONE_LEVEL_RECURSION_ is "more preferred".
It is merely described in comments in cf/m4/proto.m4 file.
sendmail-8.14.5/cf/m4/proto.m4 file:
#v+
1062 ifdef(`_VIRTUSER_STOP_ONE_LEVEL_RECURSION_',`dnl
1063 dnl this is not a documented option
1064 dnl it stops looping in virtusertable mapping if input and output
1065 dnl are identical, i.e., if address A is mapped to A.
1066 dnl it does not deal with multi-level recursion
#v-
sendmail.mc line to use it:
define(`_VIRTUSER_STOP_ONE_LEVEL_RECURSION_')dnl
virtusertable lines to make it work (as I understand it):
us...@example.com us...@example.com
us...@example.com %0
P.S. I prefer more detailed replies for benefits of future readers of
ancient postings archives.
