I proceeded assuming I could have a v2.3.10 frontend with older v2.2.13
backends. However, I was unable to get the APPEND command to work. With
telemetry logging enabled, I discovered that a 2.3 frontend issues the
IMAP command "Localappend" to a backend. However, my v2.2.13 backend does
not recognize "Localappend" as a valid command (and it is not present in
the source code).
If the email client supports referrals (and I wanted to allow referrals),
then the client is referred to the correct backend, issues the "Append"
command to the backend, and all is well.
I guess I'll have to upgrade the backends first. :(
Has anyone else done an upgrade of a Cyrus Murder from v2.2 to v2.3? What
steps did you take?
