Hi all,
I've recently set up a specialised mail server that listens on port 443 (because the infrastructure it's on won't allow it to listen on port 25). I've configured LimeSurvey (running on LimeSurvey Professional (previously LimeService)) to use it, but it apparently can't reach it (Error Message: SMTP Error: Could not connect to SMTP host.) No connection of any kind is received from the server side.

In LimeSurvey, the settings are:
Email method: SMTP
SMTP host: 115.146.<see below>.182:443
SMTP username:
SMTP password:
SMTP SSL/TLS: Off
SMTP Debug: Always

(The missing part of the IP address above is eighty-five.)

I can connect to this server fine from my laptop, so I'm wondering:
1) Is there some reason LimeSurvey/LimeSurvey Professional (previously LimeService) would refuse to connect to this server on this port?
2) Could someone try to connect to this mail server? You can't actually send mail to anyone, but would love to know if you can at least connect.

My first thought here is that the standard SSL port allows for a browser to connect, but there may not be any SMTP service available at that point. Try this: technet.microsoft.com/en-us/library/aa99...28v=exchg.65%29.aspx (yes, I know it is for Exchange, but the telnet and SMTP answer should be the same). Post your results.

TCP port 443 is the default port used by HTTPS. If this port is blocked on any server or device from your computer to a given destination, such as www.Microsoft.com , your connection to any https site will fail and your browser will return an error message like "Secure Connection Failed" or "Page Cannot be Displayed" . However, the two most common locations for this failure are at your workstation or router. Moreover, if you can access the html page at your root domain (say example.com/ ), but pages in a directory like example.com/ give you a 404 Not Found error.
