Not able to connect to mail server

Postby sun » Tue Sep 05, 2017 9:14 am

Hi,

I've installed exit/dovecot/clam/spamassassin on my existing vestacp install.

The hostname that I'm using is ns1.bookdlook.com

I had an existing client domain (chewcentral.com), and he now requested for mail so I've created a new mail domain using the same name as the web domain. I had no issue in creating the user account. However, I'm not able to logon to server using the credentials.

Here is what https://www.checktls.com/perl/live/TestReceiver.pl returns:
Trying TLS on ns1.bookdlook.com[23.111.156.114] (1):

Could anyone please guide me as to how can I correct the issue.

I am getting certificate error while trying to connect via a mail client. Also the webmail address chewcentral.com/webmail does not exist.

Resolved it by changing exit configuration.

However, now I'm facing the issue that created users are not found. Also, webmail link doesn't work (returns a 404). Has anyone been able to resolve it?
