Email send failed on certificate error - fixed for me

[#1]

Thought I’d put a one-line solution for the less technically minded like me.

I’m a Plusnet / Greenby user accessing email on Android through K-9 Mail app for a few years now with no issues.

Sending emails failed this week with certificate error. Trawling here gives lots of multi-post multi-page answers full of wordy detail that I barely followed but I managed to extract:

Go to Outgoing Server Settings in your mail app.

Change “relay.plus.net” to “mail.enmail.co”

That’s it.

No, I don’t know what  “mail.enmail.co” is, I just copied it from another thread.  If it doesn’t work for you you’ll have to look for proper experts.

Good luck!

For clarity.  This is not a fix - it is a circumvention.

In scenarios where email client auto-configuration selects the servers, this might not work / stick.

It is only going to work for those who have their email migrated to Greenby.

I am not sure an additional thread adds value.

It would have saved me an hour wading through stuff I didn't understand for the suggestion buried deep somewhere.

One hour, poor you !
