Re: Connection to IMAP server failed.

Is "mail.efurtherance.in" a remote IMAP server or just localhost?
Please check the IMAP server configuration, make sure it supports SSL on port 993.

Re: Connection to IMAP server failed.

Hi ,

Thanks for your reply.

I have installed all the applications on the same server, so mail.efurtherance.in is localhost.

"Please check the IMAP server configuration, make sure it supports SSL on port 993"
Could you advise what exactly i have to check and on which file? I have not changed anything from the original settings. Also i have followed the guide and installed letsencrypt certificate for the domain mail.efurtherance.in and updated the certificate path on all 3 config files.

/etc/nginx/templates/ssl.tmpl
/etc/postfix/main.cf
/etc/dovecot/dovecot.conf

and the port 993 is open on the server.

Thanks
Arun

Re: Connection to IMAP server failed.

Check file /opt/www/roundcubemail/config/config.inc.php, use 127.0.0.1 as your IMAP server address, like this:

$config['default_host'] = '127.0.0.1';
