[exim] .forward and aliases

Hi,

Exim 4.5

I have an alias set-up as below:

jbloggs:     jbloggs
joe:        jbloggs
joe.bloggs:    jbloggs

I have been trying to get the out-of-office message for joe. When I
email jbloggs@??? the .forward file works. If I email
joe@??? it doesn't.

Is the a variable or similar I can use to get all the aliases to
resolve?

TIA,
Dp.

======= .forward file ========
# Exim filter <<== Do not remove this line!

if error_message then finish endif

  if personal then
    mail
     to $reply_address
     subject "I am on holiday"
     file $home/vacation/message
     once $home/vacation/once
     once_repeat 7d
  endif
