Since 2001 I've been using Lotus Notes client software R5.0.12 stand-alone to manage my internet access and data bases with no issues. I run using the "Notes with Internet Access" mode and have not problems since working with IBM back in 2004 on PMR51333,1LD to add authentification mods. My Customer Id # is still #xxxxxxx, Gmail is now my primary ISP and my email address now is firstname.lastname@example.org alt. Xxxxxxx@comcast.net.
Until July 28 I've been able to read my email with my Lotus Notes client using Pop3 or IMAP protocol. Sometime after 07/28/2015 I've been receiving a "Bad Peer Certificate" errors when attempting to download my emails whether by IMAP or Pop from Gmail. I still can SEND email with SMTP because Gmail's SMTP server still has a port that supports SSLv3 but I can not pull my Gmail emails into my PC any more.
What has happened is Google/Gmail has "turned off" the SSLv3 protocol for its Pop and IMAP servers shortly after 07/28/2015, apparently due to the security worries raised by "Padding Oracle On Downgraded Legacy Encryption (POODLE) concerns (RFC7568). And that is likely why I'm seeing these certificate errors now. I understand SSLv3 is being phased out and replaced with TLS.
One fix would be for Gmail to provide fall-back ports on their IMAP and PoP servers that still support SSLv3, and I've suggested this in the help forum at https://productforums.google.com/forum/?utm_medium=email&utm_source=footer#!msg/gmail/LtD8sfbazQs/CTA-ucPPmvQJ
, but I'm coming to the conclusion that Google/Gmail is unlikely to do this.
A work around would be to forward incoming emails from Gmail to an alternate ISP (Comcast) which I can still read from. But this is cludgey and has separate issues of its own including whether Comcast will eventually abandon SSLv3 as well.
What I really need then to do is install an updated Lotus Notes Replicator module that will support the TLS protocols; TLS1.0[RFC2246], TLS1.1[RFC4346} and/or TLS1.2[RFC5246] in addition to the SSL ones. I'm hoping there is a Replicator that does this modular enough to link/plug into my R5.0.12 Lotus Notes client. If not I do have the installation disks for Lotus Notes client 6.5.1 if that release could be used, otherwise I'd have to acquire a new release but one that would have to work under Windows XP Professional SP 3 on my IBM 350 PC which has no PAE/SSE2 expanded instructions, 133MHz clock, 144MB expanded memory and 88GB hard drive (a "Hot Rodded Model T"). And of course I'd want it to be able to access my R5.0.12 NSF databases.
Any feedback as to a way to proceed would be appreciated. PMR #01186,082 was entered to formally document this problem.
