I tried


but it said

Ports other than 443 not supported

I need to check imap.spamarrest.com:993

  • do you need a site or can you run a tool on a machine? – schroeder Jun 21 '15 at 20:52
  • I can run a tool on my machine, but I thought a site would be more authoritative and configured correctly, and up-to-date, and easier to use. – Chloe Jun 21 '15 at 20:58

    I recommend to use sslyze. – sebix Jun 21 '15 at 21:06
  • What do you want it to analyze? What results are you expecting? The same range of results that ssllabs.com provides? – schroeder Jun 21 '15 at 21:07

Try https://HTBridge.com/ssl

Update 2016-02-08: New kid on the block: High-Tech Bridge does custom ports: Example: Report for imap.spamarrest.com:993

There are a few. But none even close to what SSL Labs does.

Here's two sample sites.

EDIT 2015-06-30: Port 443 limit by design.

SSL Labs does this on purpose. I didn't know this. But here's the rationale. It's listed inside their Read This First document:

Commonly Requested Features

  • Checking of IP addresses without hostnames; SSL Labs is designed to test public web servers services. We define public as having a DNS record and running on the official port for the given service (e.g., 443 for HTTPS). We don't allow direct checking of IP addresses because we don't consider such services public.
  • Checking of web servers on non-standard ports; see the previous point.

I use https://testssl.sh/

testssl.sh is a free command line tool which checks a server's service on any port for the support of TLS/SSL ciphers, protocols as well as recent cryptographic flaws and more.

It also works well on Windows 10 if you have the 'Windows Subsystem for Linux' installed https://msdn.microsoft.com/en-gb/commandline/wsl/install_guide
