Hi Kevin, Thank you for the reply.
> Are you actually listening with SSL on localhost? Is your webserver > configured to listen and allow that through to RT? 443 is listening on localhost. As you suggested, we tried curl from the localhost with both the FQDN and localhost URLs. We had limited success (without any message content), but it still fails with rt-mailgate. I suspect we need some content to test it further with curl. Do you have a sample curl command line with post params for testing? user@rt:~$ curl -I https://rt.fully.qualified.domain.name/REST/1.0/NoAuth/mail-gateway HTTP/1.1 200 OK Date: Mon, 04 Aug 2014 17:09:29 GMT Server: Apache/2.4.7 (Ubuntu) X-Frame-Options: DENY Vary: Accept-Encoding Content-Type: text/plain; charset=utf-8 user@rt:~$ curl -I https://localhost/REST/1.0/NoAuth/mail-gateway HTTP/1.1 200 OK Date: Mon, 04 Aug 2014 17:10:29 GMT Server: Apache/2.4.7 (Ubuntu) X-Frame-Options: DENY Vary: Accept-Encoding Content-Type: text/plain; charset=utf-8 Running rt-mailgate with fetchmail: 2 messages for RTUSER at hostmaster.fully.qualified.domain.name (36925 octets). fetchmail: POP3> LIST 1 fetchmail: POP3< +OK 1 34826 fetchmail: POP3> TOP 1 99999999 fetchmail: POP3< +OK reading message rtu...@hostmaster.fully.qualified.domain.name:1 of 2 (34826 octets) #**********************************.***********************************.********************************.*************.*************.*************.*************.*************.*************.*************.**************.*************.*************.*************.*************.*************.*************.*************.**************.*************.*************.*************.*************.*************.*************.*************.**************.*************.*************.*************.*************.*************.*************.**************.*************.*************.*************.*************.*****/opt/rt4/bin/rt-mailgate: temp file is '/tmp/63WuokOupY/OIpKtEaLCc' /opt/rt4/bin/rt-mailgate: connecting to https://rt.fully.qualified.domain.name /REST/1.0/NoAuth/mail-gateway HTTP request failed: 500 Can't connect to rt.fully.qualified.domain.name:443.
