I have configured Sendmail as my SMTP server at port 25.
Now I have enable dovecot for IMAP, IMAPS, POP3 and POP3S server.
Now IMAP service must be available at port 143 when I start the dovecot service in RHEL 4 ES.
But when I execute the commands for checking the status of the service it says the service is locked with subsys process.
I have a free port 143 and no other IMAP server is installed as well as configured on my system. What is the problem ?
Please Help !
For securing IMAP I have created a digitial certificate in /usr/share/ssl/certs and have copied it into /usr/share/ssl/private directory. Now to enable user to only use IMAPS should I make the entry within the /etc/dovecot.conf like:
protocols = IMAPS
or can I use IMAP and IMAPS both and still force the user to access IMAP services through the server using IMAPS and not IMAP.
One more question is mail.yahoo.com having IMAPS server. Because when I tried to login to mail.yahoo.com from a browser it showed me a certificate and only after clicking OK I could well pass that. It will be very helpful to me if someone answers my questions.
The following messages were written in /var/log/maillog when I start the dovecot service:
Jan 22 21:44:04 station12 dovecot: Dovecot starting up
Jan 22 21:44:05 station12 pop3-login: Can't load private key file /usr/share/ssl/private/dovecot.pem: error:0B080074:x509 certificate routines:X509_check_private_key:key values mismatch
It told me that I am having a problem with the certificate.
I went to /usr/share/ssl/certs directory.
Runned this command "make dovecot.pem"
Filled in the values asked by the above command and copied the file generated (dovecot.pem) into /usr/share/ssl/private directory.
Now I started the service again and this time it started successfully.
I posted this reply because maybe somebody else can get helped in future
