<div dir="ltr">I've tried a few different ports but back on port 25 now, I can telnet in but an EHLO command hangs (that used to work until recently). I'm also getting TLS errors - so I think the problem stems from changing the FQDN (I sold a dot org domain and registered the dot im equivalent last week). I generated new certs with Let's Encrypt and modified the MX / DNS records and config files but think a fresh install is probably easiest - I've tinkered with too many files to keep track now!<div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, 23 Jan 2024 at 10:00, Daniel Ankers <<a href="mailto:md1clv@md1clv.com">md1clv@md1clv.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div dir="ltr"></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, 22 Jan 2024 at 18:32, Graham Allott via IoM <<a href="mailto:iom@mailman.lug.org.uk" target="_blank">iom@mailman.lug.org.uk</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">If anyone has any tips for setting up Postfix / Dovecot on Gentoo I'd be happy to hear them - it was working with one virtual domain but changed the main domain and everything's broken....
