Bug#276126: exim4-daemon-heavy: [headers_remove] allow option to exists multiple times

[Jari Aalto]

Package: exim4-daemon-heavy
Version: 4.34-4
Severity: wishlist

I was writing code like this to the outgoing SMTP transport:

remote_smtp:
  debug_print = "T: remote_smtp for $local_part@$domain"
  driver = smtp
.ifdef MY_SMTP_DISABLE_SENDER
  headers_remove = Sender
.endif
.ifdef SA_EXIM_SMTP_HEADERS_REMOVE
  headers_remove = X-SA-Do-Not-Run \
		 : X-SA-Exim-Scanned \
		 : X-SA-Exim-Rcpt-To \
		 : X-SA-Exim-Mail-From \
		 : X-SA-Exim-Version \
		 : X-SA-Exim-Connect-IP
.endif


Unfortunately option 'headers_remove' cannot be used multiple times:

    2004-10-12 09:18:00 Exim configuration error in line 478 of 
      /var/lib/exim4/config.autogenerated.tmp:
      "headers_remove" option set for the second time
    Invalid new configfile /var/lib/exim4/config.autogenerated.tmp
    not installing /var/lib/exim4/config.autogenerated.tmp to 

If possible, add support for these options, so that they could appear 
multiple times. 

    headers_remove, headers_add

This way different programs could integrate to Exim in modular manner
using ifdef's.
