My email system which I access via Thunderbird on my Mac is down.
I have a VPS at InterServer.com.
I did not change anything on my email client.
When I try to retrieve email, Thunderbird gives me this message:
Sending of password for user address removed did not succeed. Mail server [login to view URL] responded: Temporary authentication failure. [[login to view URL]:2020-10-30 00:07:00]
A developer I hired two days ago tried to fix it, but couldn't.
There is a log he provided after his most recent attempt: in the attachment.
I have no idea what it means.
I have another report from Hosting support before the server restoration, if that is helpful.
It's possible/likely that the issue is caused by an automatic exim update which is incompatible with my VestaCP.
I need this job done immediately.
It should be a simple fix for someone who has experience in this area.
