I am facing some issue with my exchange server 2013. when any user sent email to other domain (
inside our domain emails are delivering properly. ) , email is bouncing back due to delivery delay issue. when check Queue Viewer i can see emails stuck there , Error code is "error 400 4.4 7 message delayed" But, when i restart exchange server, all queued emails will send automatically. after restart, next 30 minutes emails will be delivering normally, then again it will stuck in QUEUE.
Note: There is issues for receiving emails. only sending email is facing issue.
when i check about, error 400.4.47, its related to blacklisted ip. i check our IP address using mxtoolbox, yes it was blacklisted by SPAMHAUS. i contacted them and dislisted. it was two days back, after that also i cant sent email.
Additional details:
Our Email is hosted in third party server. and we are downloading that emails in to our exchange server using "igetmail downloader". I contacted Our email hosting company, they said, Email are not receiving to their server, its stuck inside my exchange server.
Dear Experts, do you have any idea, what might be the problem, hope anybody can help me to fix this issue.
Thanks you
