Hi Harpreet, Please let us know the queues name in which emails stuck and "Additional Queue Information" of those queues.

Hi ElvisThanks for your support.Actually my IP was blacklisted. Is there anyway to get rid from blacklist in future as I have already removed IP from blacklistThanksHarpreet

Hi Harpreet, Typically, your server had been used as open relay by spammers. If the server is identified as the source of spam, it will be put in blacklist. Please check your replay restriction settings and ask the person who put your server for the reason. Thanks, Elvis
