[Exim] Mail delivery to multiple MTAs

Hello!

I am trying to figure out if Exim 4.x can forward the same mail to more
than one different MTAs at the same time. Point here is that I have two
identical MTAs and I want copy of each mail received to be forwarded to
both of them. Currently it seems that Exim 4.x supports only
primary-backup or random load sharing mechanisms between multiple MTAs.

Any ideas, tips, tricks are highly appreciated.

Kind regards,
Hristo Grigorov.
