Very important that you keep the MIME From: and MAIL FROM: rewrite to mailop@mailop.org if you are going to implement this change, so you don't trip sender domain, antispoofing, TLD banlists, DKIM, SPF or DMARC filters.
Also local permanent errors that indicates NS cannot be found, should IMHO be ignored. This because many here privately host their email servers at home... And if theres a power outage or similar, the NS will be down too, and that will in some causes trip a permanent error tough the condition is actually temporary. Only if the domain is nonexistent at the parent (which indicates unpaid domain) or nonexistent at subscribe time (misspelled domain) it should be handled accordingly. -----Ursprungligt meddelande----- Från: Graeme Fowler via mailop <mailop@mailop.org> Skickat: den 21 november 2022 13:09 Till: mailop <mailop@mailop.org> Ämne: [mailop] [Admin] Changes to list behaviour, members' spam filters etc Hello folks A list member contacted us this morning to say that they'd observed a large number of messages from mx.mailop.org <http://mx.mailop.org/> being rejected by their anti-spam/malware system. This has raised a couple of points that I need to make: 1. The list frequently discusses spam, malware, scams and such like; as a result, a significant number of messages can and will continue to contain domains, hostnames, email addresses, technicques used by scammers/spammers and all manner of key words or terms that are only too likely to trip filters. Whilst not demanding that list members add the list and/or server to any form of pass-list they may be running, it's possibly a good idea especially if you have the ability do this per-recipient. 2. I've spotted this morning that we still have postfix's 'soft_bounce' option set to 'yes'. This is an option which is used when testing and even has the comment: # NOTE: This is good for test runs, but bad in production just above it in the default config. It means that 5xx responses are treated 'softly', so messages retry. As a result of this, I will be changing that option to 'no' in the near future. THIS WILL CHANGE AUTOMATED SUBSCRIBER MANAGEMENT <--- note well! mailman *will* disable, and subsequently unsubscribe, users with too many permanent errors. It will take time, as it's setup fairly leniently, and you'll receive automatic warnings if this happens once a week for 3 weeks before being automatically unsubscribed. I will let everyone know when I've committed this change, probably later this week.
