 There are several variants to try:

1. Use header add/remove directives in ACLs and/or routers to "reinstall" problematic "References:" header if its length is too high, in hope
    Exim would fold it correctly.

Exim doesn't fold such headers correctly.

 Yes, my experiments confirm it: add_header option in ACLs produces
a single-line header, and attempt to split it artificially by "\n" results
 in stripping the tail of line (after "\n") into X-ACL-Warn: header.

Proper splitting would add "\r\n " (any whitespace after the linebreak works, and it is essential.)
