I have a client who has an Android mobile phone who is having problems with the Virtualmin postfix server and his Microsoft Outlook phone app.
When he first set it up, it was working however, now (1 day later) his phone has suddenly started asking for the password over and over again. It also doesnt download any more emails.
I note that an issue that i thought Dibbs and I had fixed has presented itself again. When i log into Outlook on Desktop PC I am seeing an SSL certificate error. The postfix mail server has started using the certificate from a Virtual Sub server that does not exist (it was deleted almost 1 year ago).
I cant seem to figure out where this certificate setting is coming from?
