We tried to alert Microsoft to a huge portion of their Hotmail IPs having no reverse DNS: https://www.reddit.com/r/microsoft/comments/mmy345/microsoft_official_support_thread/h1ax762/?utm_source=reddit&utm_medium=web2x&context=3
They asked us to open a ticket. Couldn't make this stuff up.
Today we experienced an issue with outbound mail for roughly an hour. The details are too extensive to go into here, but have been posted in our #postmortems channel at chat.mxroute.com.
This issue doesn't seem to be what it initially appeared to be. As we continue to work on it, this seems to have occurred when multiple multi domain certs were made. For example, selected Domain1 and made a cert for all domains, selected Domain2 and made a cert for all domains, selected Domain3 and made a cert for all domains. Now all 3 domains have 3 Dovecot SNI certs in conf files for each domain.
We believe we may have identified an issue with Dovecot's handling of multi-domain SSL certs. If you have one cert signed at once for more than one of your domains (for custom mail subdomain, for IMAP/POP/SMTP), Dovecot may continue to serve an expired certificate even after successful renewal. Investigating.
Banshee server is set for emergency migration as soon as possible. We're looking at hardware failure but impossible to tell how much time we have. As long as it's functioning, we're going to keep it in production and aim for a seamless migration. This is an older cPanel box, not equal to our current hardware standards. It will be post-migration.
