Subject: sat-rewrite.m4: On satellite hosts, rewrite ADDR@HOST.distorted.org.uk.
X-Git-Url: https://git.distorted.org.uk/~mdw/exim-config/commitdiff_plain/8fca6182bd0b3b877ccca2e90b75c99e75f1008e

sat-rewrite.m4: On satellite hosts, rewrite ADDR@HOST.distorted.org.uk.

These addresses are simply wrong, but stamping out programs which try to
issue them one by one is too difficult.

+## If our fully-qualified host name appears in an address then remove it.  It
+## won't work, but some programs are too stupid to send mail properly.  This
+## only gets done on true satellite hosts, because there's a plausible reason
+## for naming an explicit host if it can actually receive mail.  We apply
+## this rewrite to both source and destination addresses, because programs
+## screw up both.  This all makes me feel very sad.
