Betreff: [exim] Vacation and Exim with virutal users and domains
After having solved the initial problem with vacation and exim, I now have a new one. Tried lots to find a solution, but just keep going round in circles. Its probably so obvious that I'm missing it, so maybe another pair of eyes will see whats wrong. What I don't know is whether this is a problem with vacation or exim or both.

This is how we're set up here

Fred Jones has a log in account of fjones for his email.
The mail server has the domain name of mail.example.com
Freds email is delivered to fred.jones[at]hisoffice.co.uk

So we have a virtual domain file of hisoffice.co.uk and in it we have

fred.jones: fjones

Now, in .forward we have

\fjones, "|/usr/local/bin/vacation fjones"

and in .vacation.msg we have

From : fred.jones[at]hisoffice.co.uk
Subject : Re $SUBJECT

text...

This works fine, but the vacation email that gets returned has the return address of : fjones[at]mail.example.com instead of fred.jones[at]hisoffice.co.uk

We've tried \fjones, "|/usr/local/bin/vacation -a fred.jones[at]hisoffice.co.uk fjones" but it made no difference.

Now, ok, fair enough, perhaps I'm being picky, but for neatness it would be nice for the return address to be right.

Our forward router and transport in configure are:

userforward:
driver = redirect
check_local_user
file = $home/.forward
no_verify
no_expn
check_ancestor
allow_filter
file_transport = address_file
pipe_transport = address_pipe
reply_transport = address_reply

I've discovered that Address_Pipe gets used here

address_pipe:
driver = pipe
return_output

Any more thoughts anyone ? We're using V1.1.8 of vacation, Exim V4.66 and it's on a FC 6 system.

Thanks for the reply Bill,

The problem here is that I need to rewrite the headers for multiple
recipients so the only way how to separate them (AFAIK) is to get in emails
one by one and check the rcpt_to value.

Since I can't touch the headers yet I need to set some flags or variables,
understood

Could you please provide some simple syntax for doing so? Checking rcpt_to
against a list of users and adding a flag at SMTP time and checking this
flag at DATA (or later) time and modifying the headers? Or just point me to
some papers which deal with this thing specifically (I found few but maybe
you know more readable ones)

Can I perhaps use this new variable even in the rewrite part?

Thank you either way

At RCPT TO you don't yet have any headers....

Prior to DATA, all an smtp session has is a 'negotiation' situation.

Your MTA and the distant sender are introducing themselves, exchanging
credentials, describing what is available and what is wanted (connect,
helo, mail_from, rcpt_to).

Ever see two dogs meeting for the first time?

Much the same.

You can *prepare* headers to be substituted or appended later, and can
set flags to cause whatever you have prepped to be actioned. Or NOT.

But DATA is the earliest you are transferred the message and its headers
and attachments (if any).

That said, a flag, value, or string carried in an acl_m variable might
serve you better than header alteration.

Bill
