[Pkg-exim4-users] Removing 'names', and per-subject domain rewriting (level: newbie)

[Sebastian Tennant]

Hi list,

Firstly, I have a simple rule:

 www-data at example.host.org  system-mailer@$domain f

that changes this:

 From: www-data <www-data at example.host.org>

to this:

 From: www-data <system-mailer at example.host.org>

How can I remove the 'name' (www-data) or prevent it from being added
later?

Secondly, is it possible to rewrite domains according to a string match
on the subject header?  If so, any tips, pointers, suggestions as to how
this could be achieved would be very much appreciated.

Sebastian
