Second machine (backend with dovecot clinet) is old debian (8.11) and
2.2.32 | ( and tested 2.2.36)

telnet 10.0.0.24 143
Trying 10.0.0.24...
Connected to 10.0.0.24.
Escape character is '^]'.
* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE
IDLE AUTH=PLAIN AUTH=LOGIN] Imap ready.

and works fine

In productions i have debian 8.11 and 9.x all workings fine (this same
configurations etc)
