Error in Dovecot?

[Katronix]

Hi all, so trying to find out why I can't get my PHP scripts to log in to the mail server to send out email. I noticed that in /var/log/dovecot.log I see several lines like:

Apr 27 20:55:09 auth: Error: passwd-file(editors,108.208.116.246): stat(/etc/exim4/domains//passwd) failed: No such file or directory

would this indicate that dovecot is configured wrong?

Thanks.

I think the file /etc/exim4/domains//passwd is not found
On CentOS (what I use) folder is exim not exim4
Please do check configuration

Check or rebuild mail.

Path (on Debian/Ubuntu):
/etc/exim4/domains/domain.com/passwd

I have the same problem on CentOS 7 and Vesta 17.

stat(/etc/exim/domains//passwd) failed: No such file or directory

What is this? Why regexp not work in config file?
