Well, not as such, since it uses a '+' character, not a '-' character. I
have very little experience with qmail -- does it already provide a facility
for tacking on the '-<string>' extensions for you?
sendmail does not provide any special way to add the '+<string>'s, so it's
appropriate for nmh to handle it. If qmail handles it for you, though, we'd
have to worry about both nmh and qmail each appending a copy and getting an
address like "dan-nmh-nmh" (in case you're wondering, my "dan-nmh" address
is just a plain old manual sendmail alias to "dan" on my machine).
If qmail does not provide a facility to add the extensions, though, I'd be
happy to put it into nmh. Neil, did you say a while back that there was
another mail client that also used the $USERPLUS environment variable? If
so, and it's some kind of ad-hoc standard, I wouldn't want to rename it to
remove the word "PLUS". In this case, we could add another environment
variable called something like $USER_EXTENSION ($USEREXTENSION?) and tack on
the value with a '-'.
If the $USERPLUS variable is not sacred, I'd probably want to just have a
single variable called $USER_EXTENSION that would contain whatever string
you wanted appended, and you'd be responsible for including your own '-' or
'+' or whatever your MTA uses to separate the real account from the add-on
string...
