We are working on this -- I believe we've discovered the problem internally, it seems to be a bad link between the handoff from mailman to postfix on a large list, exacerbated by several users whose domains return a SRVFAIL response. (The irony here of course is that those users need the help the list could offer the most). This seems to be because mailman asks postfix to do a "verify" (but not an SMTP VRFY) of the addresses as part of the VERP that it does. One annoying thing that I should note is that removing those problem users and flushing the queues does NOT help. -Dan _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
