Sorry, you can't.
Exim no longer supports the ancient source-routing features. Source
routing has been deprecated for a long time now. RFC 1123 (October 1989
- well over 10 years ago) says
A Sender-SMTP SHOULD NOT send a RCPT TO: command containing an
explicit source route using the "@...:" address form. Thus,
the relay function defined in section 3.6 of RFC-821 should
not be used.
and RFC 2822 (the current specification, April 2001) says:
------------------------------------------------------------------------
4.4. Obsolete Addressing
There are three primary differences in addressing. First, mailbox
addresses were allowed to have a route portion before the addr-spec
when enclosed in "<" and ">". The route is simply a comma-separated
list of domain names, each preceded by "@", and the list terminated
by a colon. Second, CFWS were allowed between the period-separated
elements of local-part and domain (i.e., dot-atom was not used). In
addition, local-part is allowed to contain quoted-string in addition
to just atom. Finally, mailbox-list and address-list were allowed to
have "null" members. That is, there could be two or more commas in
such a list with nothing in between them.
obs-angle-addr = [CFWS] "<" [obs-route] addr-spec ">" [CFWS]
obs-route = [CFWS] obs-domain-list ":" [CFWS]
obs-domain-list = "@" domain *(*(CFWS / "," ) [CFWS] "@" domain)
obs-local-part = word *("." word)
obs-domain = atom *("." atom)
obs-mbox-list = 1*([mailbox] [CFWS] "," [CFWS]) [mailbox]
obs-addr-list = 1*([address] [CFWS] "," [CFWS]) [address]
When interpreting addresses, the route portion SHOULD be ignored.
------------------------------------------------------------------------
Note the very last sentence. Exim is doing what the RFC says it SHOULD.
Note also that support for domain literals (use of @[x.x.x.x] instead of
a domain name) is turned off in Exim by default.
