Misunderstanding "copy to xxx" SSL certs

Strange.
It’s been a while since I performed a dist-upgrade on a production server, but can’t remember running into these issues, everything was fixed magically-ish.

I only found a file in /etc/webmin/postfix/ called version, which contains the Postfix version number, but I wouldn’t change that manually, at least until a dev has chimed in with any ideas… Sorry.

This post from Ilia seems to indicate that if you’re running a current version of Webmin (which is mandatory for this to work at all, anyway), you shouldn’t need to update the version file.

How to get installed Postfix 3.4+ with SNI support on CentOS 7/8

I cannot agree more! It might cause issues, which would need some experience to fix it. We would like to point out, that we wouldn’t be able to support it. However, if you feel you want to try, go ahead and let us know how did it go. I would backed up /etc/postfix, /etc/webmin and actually complete /etc directory first. Remember, that you could always go back to stock Postfix by swapping the packages back by using yum/dnf command. Note: Only upcoming Virtualmin 6.10+ release will have SNI sup…

So, are you running current Webmin and Virtualmin versions?

It’s all fixed! I deleted /etc/webmin/postfix/version following a tip and after a restart the missing option appeared. Its great to see all the email for the domains working again. The correct version of postfix now appears in the dashboard. Thanks everyone.
