Here's the configuration I used to have, but it's a while ago that I used it:

Likely problem is SSL... There hasn't really been any SSL for past... well... many years...

All recent certs + connections will be TLS.

I don't use Outlook + most email clients have an option either to try SSL first + then TLS, or to force TLS.

If you set SSL, this means SSL2 or SSL3 + what you're really after is TLS... because...

Google does not support SSL2 + SSL3, because they're insecure + badly broken protocols.
porambokuAuthor Commented:
that's wired.. even today many open source products still use SSL 3 !!!
porambokuAuthor Commented:
so, you think there isn't a solution?
can we force notes client to use TLS?
Sjef BosmanGroupware ConsultantCommented:
Interesting documents that may give you some clues (especially the "less secure clients" part):
David FavorLinux/LXD/WordPress/Hosting SavantCommented:
If you use SSL2 or SSL3 you're just begging for problems.

There's a reason many companies like PayPal just switched (2018-06-29) to requiring TLSv1.2 as minimum security protocol they allow.

Gmail will not accept SSL2 or SSL3 connections.

I'd suggest you open a ticket with the organization providing you with Notes support + ask how to configure Notes to force TLSv1.2 so you're sure you're mail connections are accepted.

And the message you reference above...

Looks to be on a per Notes client basis, so I'm guessing where ever you setup your connection to you'll find a toggle switch for Force TLS somewhere.

Important: For this to work, you're first step is logging into the related gmail account + navigate to settings + manually enable POP.

If you don't have POP enabled, then you'll get a connection refused message all the time... which may simply mean POP in gmail is disabled + Notes is spewing a badly formed message.

Tip: Before mucking about with Notes, connect to your gmail account with an openssl client + test your gmail settings.

Way simpler to do initial debug with openssl, than a bloated tool like Notes. Use openssl + you'll get far more descriptive error messages.

Bloated? Why insult or disqualify the Asker?
Sjef BosmanGroupware ConsultantCommented:
@poramboku: can we see your Gmail setting in Notes?
David FavorLinux/LXD/WordPress/Hosting SavantCommented:
Trying to debug connections with Notes (bloated, big code) compared with using openssl (compact code) has nothing to do with insulting.

It's just stating facts.

Using Notes to debug a connection is simply the wrong tool.

The correct first tool is openssl, which is why openssl exists. The openssl library folks built this tool because debugging SSL/TLS connections can be very difficult.

Use openssl first + after you're sure all's well, then roll into Notes the exact/tested settings which you got to work using openssl.
