Greeting.

I use "vacation" in my mail server. But I had troubles when it
sends autoreplay with default hostname and ignores other virtual
domain names.

Fof fix it I made some changes. Look at :

I work with SuSE Linux and my path must add to source after SuSE-team's
patch. But SuSE's patch so simple and I hope you undestand all ( if you
need of course ;).

May be my changes will be usefull for somebody.

Cheers from Moskow.
