Email without SSL

emailgoogle-workspacepop3smtpssl

I have been trying to setup LabTech Email settings.
Unfortunately, it accepts only email settings that are not encrypted; no SSL/TLS
i.e POP 110 and SMTP 25. Tried to setup SMTPSSL in the same, but no help.

We have our email hosted on a GApps account, so there is no option of opting out of SSL.
I have read about setting up Hmail Server and STunnel but our Labtech server is hosted on an EC2 by LabTech where we dont have access to setup mail servers.

I have tried with Restricted Gmail SMTP server (aspmx.l.google.com), but POP is still a mess. Also, could not successfully figure out SMTP settings.

What i want:

  1. Any free email that allows SSL-less authentication(and forward all emails to my support email)
  2. An alternative to installing mail server on the hosted dedicated-application server(as i have no access to it)

Any any help is greatly appreciated.

Update:
Requirements:

  1. Bypass SSL authentication of GMAIL service

    or

  2. Setup to redirect mail, but could be installed outside of dedicated server

You don't have to put stunnel on your client machine or your server machine.

You can put it on either, or one in between.

It will listen on some port.

You connect the non-ssl client to that port that stunnel listens on and it will then connect to the ssl server.

Here is a snippet from stunnel.conf notice the example in there by default, uses gmail!

; Example SSL client mode services

;[gmail-pop3]
;client = yes
;accept = 127.0.0.1:110
;connect = pop.gmail.com:995

;[gmail-imap]
;client = yes
;accept = 127.0.0.1:143
;connect = imap.gmail.com:993

[gmail-smtp]
client = yes
accept = 127.0.0.1:345
connect = smtp.gmail.com:465

But notice also that the [gmail-smtp] (what you want), only connects to port 465 which is ssl without starttls https://stackoverflow.com/questions/15796530/what-is-the-difference-between-ports-465-and-587

It seems stunnel only supports that form of ssl..

But that's OK because gmail supports that (on port 465).
