I've been struggling trying to get Thunderbird to read e-mail off a 
CentOS 7 server.
Sendmail writes mail in /var/spool/mail
I've configured dovecot to try to read from there using Thunderbird 
(POP3/SMTP).
The firewall allows ports 25/110.
I verified I have mail in /var/spool/mail
but Thunderbird is unable to retrieve that mail.
I've googled sendmail / dovecot config, I've looked a the wiki but I 
just can't figure this out.
Please don't suggest using postfix, I just want to get sendmail / 
dovecot working.

Should your INBOX path be /var/spool/mail/%u then?
