How do I add more aliases to my .forward vacation file?

[Andreas Widerøe Andersen]

Hi,
How can I add more than one alias to my .forward vacation file?

I have an email address that has two aliases in addition to the username. I
receive mail to all and would like to know how (if) I can add another alias.

My .foward file is like this today:

\myusername, "|/usr/bin/vacation -a myalias myusername"

I have tried a few things, but just get error messages.

Thanks!
Andreas
