Mail delivery failed: returning message to sender
Hi Guys,
Are you familiar with this error below? Can I have your idea to resolve this? Our domain got blacklisted but already delisted since yesterday by availing Deliver Center from MXTOOLBOX. But we still encountering bounce-back email today in some domain.

This is the key statement - your server could not connect to the destination server, and the message ended up frozen in the queue. See Mail Queue Manager - Version 74 Documentation - cPanel Documentation for full details0 -
Further to what was indicated by @rpvw it's also possible that your server is unable to connect to the recipient server due to the blacklisting still. Sometimes you can see residual effects of this for days, depending on the configuration of the recipient domain. They could be using a private blacklist or their own set of rules to determine what mail to accept. 0 -
