I'm having major difficulties with an email account set up on a domain we host. The person can't access emails on a Blackberry. I've set up the same email account in Outlook, on an iPhone, on a Samsung Galaxy all of which work fine. We've contacted Blackberry who directed us to a webpage listing the settings for this particular device. It showed that the settings are pointing to port 955 using SSL. The correct port should be 25 with no SSL. They are saying they can't change the ports? Is there anything I can do without having to make everyone else on the same domain change their settings?
"It showed that the settings are pointing to port 955 using SSL." You probably mean port 995, not port 955. Check if Port 995 is open using the following command from a linux box: nmap -P0 -p995 yourdomain.com If it is open, you should try to configure your Blackberry to use port 995 (POP3S - POP3 protocol directed through an SSL layer). If port 995 is closed, try using port 110 (POP3) or configure your Plesk by following the instructions at http://www.nightlion.net/guides/2010/ssl-certificate-setup-for-pop3s-imaps-smtps-on-plesk/
