To speed things up a bit, I have adapted the exim-4.50-r1.ebuild for new mailer-config scheme. I'm attaching the ebuild, diff, and new a .mailer config file. Colin, Jay, I can even add this ebuild to portage if you allow me to. Of course it will be package.mask-ed, until the day D, when we unmask mailer-config aware ebuilds for all big MTAs.
Created attachment 62427 [details] The full ebuild
Created attachment 62428 [details] The diff from exim-4.50-r1.ebuild
Created attachment 62429 [details] File to be installed as /etc/exim-${PV}.mailer This should obviously go into ${FILESDIR}.
Created attachment 62430 [details, diff] The unified diff to exim-4.50-r1.ebuild Sorry, I omitted the -u option from diff by mistake before.
Created attachment 62630 [details, diff] An updated diff (rmail being handled) against 4.50-r1 As I'm still working on all the MTA ebuilds, here is an updated diff to exim-4.50-r1.ebuild. This one doesn't install /usr/bin/rmail, /usr/lib/sendmail, /usr/bin/mailq and /usr/bin/newaliases if mailwrapper flag is on, but instead this is handled by an updated files/mailer.conf (attached next).
Created attachment 62631 [details] Full ebuild (rmail handled)
Created attachment 62632 [details] Updated files/mailer.conf file (rmail handled)
Since there has been no response, I've added this to portage, package.masked, of course.
