Running lsof -i :143, I get:

COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
dovecot 1576 root   37u  IPv4  32014      0t0  TCP *:imap (LISTEN)
dovecot 1576 root   38u  IPv6  32015      0t0  TCP *:imap (LISTEN)

Running ss -tulpen | grep 143 :

tcp    LISTEN     0      100       *:143                   *:*
users:(("dovecot",pid=1576,fd=37)) ino:32014 sk:ffff913e953e2e80
