Hi,
I'm hoping someone can help out as this issue is causing serious issues within my company.
We upgraded from Exchange 2003 to 2013 recently and everything was fine for a start, but in the last week we have had numerous problems sending email to certain customers (from various companies) and get the error email below:
CO1EHSMHS030 bigfish com rejected your message to the following email addresses:
Service unavailable; Client host [xxx.xxx.xxx.xxx] blocked using Blocklist 1, mail from IP banned; To request removal from this list please forward this message to delist messaging microsoft com and include your ip address xxx.xxx.xxx.xxx.
(PS '.' and @'s removed as I can't post links yet)
Your message wasn't delivered due to a permission or security issue. It may have been rejected by a moderator, the address may only accept email from certain senders, or another restriction may be preventing delivery.
We have obviously tried emailing the delist@ address as stated (more than once), but all we ever get is an automated response and stating we will be contacted within 24 is there are an problems...and of course we receive nothing.
This has been going on for a whole week now and it is seriously effecting our relationships with clients. Can anyone help? Who do I contact to get this resolved?
