Hi everyone,
I'm running a test environment with a proxy in front of working
replication between two backends but redirecting in case of a
backend failure is not working.
Nov 09 21:03:59 imap-login: Error: proxy(m...@example.net):
connect(10.5.29.211, 143) failed: Connection refused (after 0 secs,
local=10.5.29.201:38333)
I appreciate any advice.
Regards
Patrick
