# /etc/init.d/dovecot start
Starting IMAP/POP3 mail server: dovecotError: mail_executable: Can't use /usr/lib/dovecot/imap: No such file or directory
Fatal: Invalid configuration in /etc/dovecot/dovecot.conf
failed

and this is the line for the which is error in the dovecot conf:

# Login executable location.
#login_executable = /usr/lib/dovecot/imap-login

this is what is in the /usr/lib/dovecot:

/usr/lib/dovecot# ls
authtest dovecot-auth listview modules
checkpassword-reply expire-tool logview rawlog
convert-tool expire-tool.sh maildirlock ssl-build-param
deliver gdbhelper managesieve threadview

That line is not the problem with dovecot.conf, it is currently just a comment, and is ignored.
Recheck the lines you changed.
This is mine.

Code: Select all

# dovecot -n

Thanks for the reply , the deovecot -n is not working:

dovecot -n
# 1.2.15: /etc/dovecot/dovecot.conf
Error: mail_executable: Can't use /usr/lib/dovecot/imap: No such file or directory
Fatal: Invalid configuration in /etc/dovecot/dovecot.conf

I check out the dovecot.conf manually for the mail_executable and find tree one's and that are these:

#login_executable = /usr/lib/dovecot/imap-login
#login_executable = /usr/lib/dovecot/pop3-login
#login_executable = /usr/lib/dovecot/managesieve-login

I think this is the default path for the login_executable in the dovecot.conf.

Maybe uncomment this

Code: Select all

#login_executable = /usr/lib/dovecot/imap-login

The error says

Code: Select all

Can't use /usr/lib/dovecot/[b]imap[/b]

Or purge dovecot (so configs are removed) and reinstall the defaults again.
