The RFCs require this facility. However, it is +# little-known these days, and has been exploited by evil people seeking +# to abuse SMTP relays. Consequently it is commented out in the default +# configuration.

Note +# that 0.0.0.0 is the same as 0.0.0.0/32, which is commonly treated as the +# local host inside the network stack.

You can do +# this by uncommenting the "user" option below (changing the user name +# as appropriate) and adding a "group" option if necessary. Alternatively, you +# can specify "user" on the transports that are used.

If you want it also to allow mail filtering when a forward +# file starts with the string "# Exim filter" or "# Sieve filter", uncomment +# the "allow_filter" option. + +# The no_verify setting means that this router is skipped when Exim is +# verifying addresses. Similarly, no_expn means that this router is skipped if +# Exim is processing an EXPN command. + +# If you want this router to treat local parts with suffixes introduced by "-" +# or "+" characters as if the suffixes did not exist, uncomment the two local_ +# part_suffix options.
