Careful wording there, with "should" :) For "may", I reference RFC2782 section "The format of the SRV RR" para "Service" and STD 2 (RFC 1700) section "PROTOCOL AND SERVICE NAMES". I wasn't trying to imply that doing it is normal practice, and Exim's default is not to. -- Jeremy -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
