Amazon SES: Hangs at the end of each group?

[stanbusk]

I posted a prerelease link. Did you try it? It is supposed to fix the problem.

Same problem here. MBM (ver. 8.4.6, Mac) is randomly unable to reconnect next SMTP session following countdown after previous session termination.
Error message is the same as already reported in posts above: 535 Authentication Credentials Invalid

Update: actually it seems that (after some long trial with differente MBM connection settings...) my problem has been fixed by selecting ESMTP >> Plain << authentication.
That seems to be the only way to make it work flawlessly without continuously stopping randomly with "535 Authentication Credentials Invalid" error when opening smtp connection.

I also discovered the following MBM help page:
http://www.maxprog.com/site/support/us/ ... on_ses.php
stating that ESMTP with "Login" option should be used, but it does not work for me.
Only way is to choose "Plain" instead of "Login".

Actually both PLAIN and LOGIN should work... weird... :?

I'm having this same issue, running 8.4.7 on Mac. I can get emails out, but most of the time I get an authentication error. Seems that I can get one clean run in and then everything dies. Note that I've gotten a test email out to all recipients (including a few CCs) and even the "report." But a single run is all I get before I get the 535 error.

Here's the log I'm getting:

Set a larger delay between groups.
