Terjadi salah password karena email client tidak mendukung protokol 
CRAM-MD5/APOP.

Agar tidak terulang, non aktifkan menu berikut di MDaemon.

https://mdaemon.dutaint.com/mdaemon/25.5.0/default-domain-and-servers_servers.html

[ ] Enable APOP & CRAM-MD5

By default MDaemon's servers (POP, IMAP, and so on) do not honor the 
APOP and CRAM-MD5 methods of authentication. This type of authentication 
requires passwords to be stored using reversible encryption, which is 
not recommended for security purposes, in order to protect passwords 
from being decrypted by MDaemon, the administrator, or a possible attacker.




Ini masih sama seperti ini pak sudah saya uncheck pilihan  [ ] Enable APOP & 
CRAM-MD5
