I have configured dovecoat on centOs. When i access email through thunderbird or gmail IMAP. everything goes fine. but when i try to configure using sparrow mail client on Mac osx. Server log shows the below error.
Nov 16 12:40:07 localhost dovecot-auth: pam_unix(dovecot:auth): authentication failure; logname= uid=0 euid=0 tty=dovecot ruser=info@xyz.com rhost=82.16.29.165

Everytime mail client tries to fetch emails, it just throughs the below log.
