[SM-PLUGINS] Yelp fails silently

[Bob R. <rri...@bl...>]

Hi:

Have configured Yelp as per the Docs. The only config change is the adress
to which Yelp reports to.

The Docs show an example for mail() thus: mail (user1, user2, ...
Since I run a set of virtual domains mine looks like: mail
(us...@do...d, ...

Yelp "SEEMS" to work, but no email is ever sent; no errors either.
It seems as if the "mail()" function is not working, as the rest of
Squirrelmail sends mail fine.

PHP 4.3.4
Squirrelmail 1.4.2
apache 2.0.48
UW IMAP compiled for Vdomains: IMAP4rev1 v12.264.phall

Any help/hints would be appreciated

Bob
