First up: looks like we had a moderation backlog, and new subscribers are moderated by default, so your message was stuck in moderation for far longer than normal. Sorry about that. Your moderation bit has been cleared.

RFC 5321 section 6.3 agrees with you. 30 has served us well for some time and I don't think it's scaling quite that pessimistically: mail routing tends to be _simpler_ in many flows than it was years ago, as borders mail directly to each other, while chained mailing-lists are rare. Thus there's usually two administrative domains to care about, or three with a mailing-list in there. Your points about the increased complexity _within_ an ADMD, particularly with outsourcing of some components, are sound. I myself have only ever seen 30 reached when there's been a loop, but raising the default to 100 is reasonable IMO. Anyone object? Basis for objection? If objecting, alternative proposal? -Phil -- ## List details at https://lists.exim.org/mailman/listinfo/exim-dev Exim details at http://www.exim.org/ ##
