[BETA Build 7338] Users reporting issues with POP3 now
Problem reported by echoDreamz - 2/4/2020 at 2:13 AM
Resolved
We've had quite a few clients all reporting issues with Tbird, Samsung's native mail client on Android and TypeApp on Android and various other email clients, shortly after we did the 7338 build.

Tbird is saying...

Sending of username did not succeed. Mail server ADDRESS responded: Capability list follows
TypeApp simply reports that it failed logging in. This SM build isnt crashing, but it would appear that POP3 is possibly broken. It's late, so I assume as we get into US business hours our support load is going to skyrocket.

FIXED: Outlook 2007 and base versions of 2010 have issues authenticating via POP.
Wondering if it has to do with this fix here.

Hey Chris, it would be related to that fix.  We'll take a look at it today.

Thanks! Have you guys found any fixes for this? Our users are about ready to burn us to the ground.

This still appears to be an issue. We have some clients running WHMCS saying they are getting error...

Connection error: Server bug: non-empty initial PLAIN challenge Host: REMOVED
WHMCS support is stating...

Hello!

Looks like your server is implementing SASL-PLAIN incorrectly or in a way that your library doesn't like.
The clients logs also show this started failing the same time we installed the previously broken release.

Hey Chris, we'll take a look at it.  I know Thunderbird was one of the clients that was reported as having issues and we tested against this without any issues.  Do you know what library they're using?  That might help us figure out what the actual cause is in our implementation.

The error returned looks like an error returned by php's built-in pop3/imap connector.

Probably a problem with one of the two methods described here:

Thanks Sebastien.  That leads to what we were thinking.  We were returning a POP3 SASL PLAIN response with an "OK" in the response and I'm thinking that's part of the problem.  I'll get a custom build over to Chris and we'll see if that change fixes it.

Marked As Resolution
This has been fully resolved, including a bug with POP3 authentication using the mailbox+folder_name has also been fixed.
