Apologies to ask, but I saw in the news information that the latest virtualmin update comes with, quoting: “Per-domain SSL certifcates can now be setup in Postfix, if running version 3.4 or later.”
I do happen to run postfix 3.4.10 on a Debian 10, however I am unable to find where this option might be present in virtualmin…
I’m sorry to ask, but could someone point me in the right direction, please?
I’m not asking without a reason. It’s been more than a month (maybe a lot more, I didn’t try before) that I noticed that the gmail app is unable to send mail for virtualmin-managed domains.
In gmail’s app, sending mail section, if I give the server’s reverse (as mentioned in webmin > servers > postfix > general options > internet hostname) and the proper account’s password, gmails throws a certificate not matching error and refuses to make an exception. And if I give instead mail.domain.tld, it used to work a few months ago, but now it’s not working anymore either, also certificate not matching (and yet, I made sure to include mail.domain.tld to be part of the letsencrypt certificates for that domain).
So, I told myself it might be related to virtualmin. Not sure at all, but who knows, maybe it is.
