Had v3.8 running ok until something odd happened last night. v4.2 was not
going to install without a big fight, so installed 4.18 (which only put a
struggle ).
tsupport@myurl.com: temporary failure. Command output: An Error Occurred
================= 403 Forbidden
Is this an apache config issue or something else?
Have you looked in your apache logs?
If you searched the mailing lists for rt-mailgate and 403, you’d see
that I normally reply that this sounds like you’re telling rt-mailgate
to connect via http while apache forces https and you need to tell
rt-mailgate to use https (or allow rt-mailgate another connection
option).
