Maybe update this to having multiple ports (if this is even possible)
frontend ft_imap
bind :110 <<
bind :143
mode tcp
default_backend bk_imap
backend bk_imap
mode tcp
balance leastconn
stick store-request src
stick-table type ip size 200k expire 30m
server s1 backend.example.com:10143 send-proxy-v2 <<< how to put more ports
here?
