[dev] patch for vacation .forward driver

[Peter Arien]

When I install a vacation message, I get a horde.warning notification
telling me "Your vacation notice is currently disabled."
Not good, because the vacation message _is_ correctly installed.

The forward driver installs the following .forward file:
\m2000953, "|/usr/bin/vacation -a peter.arien at student.kuleuven.ac.be m2000953"

The first part ("\m2000953") is recognised as a valid email address
by Mail_RFC822::parseAddressList, and put in $adr->mailbox, but the
second part is not recognised, and thus not put in $adr->mailbox.
The preg_match will never succeed, because it matches $adr->mailbox,
but at that time $adr is a string, not an array.

Whatever, the attached patch solves this for me.
