Hello. I'm a long time user of ISP, usually I figure out how to solve my issues (thanks to this forum most of time) but here I'm really stuck. The short story : - I installed a new server using the automated script (Ubuntu 20.04 / Nginx) and chosen to give a try to "rspamd" instead of the usual Amavis - Everything went well, so next I exported / imported the mailboxes from the old server to the new one using the ISP API/Script and a rsync of 'vmail'. - No issue with the migration, mailboxes are here BUT delivery does not work because of a "connect to 127.0.0.1[127.0.0.1]:10024: Connection refused" error. - BUT delivery works for new created mailboxes I started digging every where, what I've tried : - forced update of ISP with "reconfigure services? yes" - changed setting to Amavis, saved, then set it back to Rspamd and saved again, mailboxes where updated, but nothing changed - "grepped" entire /etc to find "10024", only find something in "postfix/tag_as_foreign.re", removed, restarted postfix/clamav, no luck - "grepped" the entire database to find "10024" but nothing - "grepped" inside an imported mailbox to find "10024" but nothing So the question is : where could be this filter for these imported mailboxes ? Does not seem to be in /etc, not in the DB and not in the mailbox itself... it's driving me crazy. Thanks for your suggestions EDIT: - in fact I've both "connect to 127.0.0.1[127.0.0.1]:10026: Connection refused)" and "127.0.0.1[127.0.0.1]:10024: Connection refused" errors - forgot to said that Rspamd is working well (for the new mailboxes) - and that I checked https://www.howtoforge.com/replacing-amavisd-with-rspamd-in-ispconfig/ but nothing is said about updating a setting in the existing mailboxes EDIT2: it was well the 2 filters setup in ./postfix/tag_as_originating.re and ./postfix/tag_as_foreign.re because by removing them new mails are well delivered so the questions are now: - why these filters were here? - how can I tell postfix to ignore these filters in the queue (as the mails seem "tagged" only here now)?
