HI there I have been having a few bounces due to this error.

smtp; 554 4.4.7 Message expired: unable to deliver in 840 minutes.<450-4.2.1 The user you are trying to contact is receiving mail at a rate that<CRLF>450-4.2.1 prevents additional messages from being delivered. Please resend your<CRLF>450-4.2.1 message at a later time. If the user is able to receive mail at that<CRLF>450-4.2.1 time, your message will be delivered.

I am actually running into this same error. We have over 5,000 SOFT bounces and a majority are:

Message expired: unable to deliver in 840 minutes

I don't think MailWizz will update these to blacklisted because they are soft bounces, right?

How should we handle these to cut down on our bounce rate?
 
@Jeremy - If you get same soft bounce for an email 5 times, mailwizz will blacklist them, but as it stays now, looking at the bounce message, those messages should be retries not removed, it seems the issue is with your smtp server which cannot handle the delivery process.
