The last 2 years this issue has been steadily increasing where my colleague's xneelo hosted server is unable to send emails to Microsoft hosted domains due to being in their block list.
Typical error code:
host hotmail-com.olc.protection.outlook.com [52.x.x.x]
SMTP error from remote mail server after pipelined sending data block:
550 5.7.1 Unfortunately, messages from [x.x.x.x] weren't sent.
Please contact your Internet service provider since part of their network is
on our block list (S3150).
Then he emails them and they answer roughly 8-10 hours later saying that they have rotated out the offending IP address from the sending pool, so people can now resend their emails.
In the meanwhile, a day has passed where tons of emails are unable to go through.
Lately this issue has been happening at a much increased pace and there were 2 affected days last week, and now again today.
Their answer has been to use the ISP's SMTP server.
(Ok, but some of the business ISPs don't have open SMTP servers or they don't know what they are. Also, isn't the service xneelo offers offering receiving and sending emails?)
Each time it happens he gets a barrage of messages / calls from people demanding to know what the issue is and that they have urgent emails that must be sent. So a few hours of the day is now wasted on placating customers and checking each query if it's related to the Blocklist or something else.
Now because this happens, if users make a spelling mistake tomorrow they'll also send the email error in thinking it's probably also due to the "usual blocklist issue", increasing the volume of calls.
Considering the cost of a couple of thousand per month for a dedicated server to primarily send and receive emails for a bunch of people the sentiment is souring with xneelo as the problem is not being resolved and the frequency has been rapidly increasing.
On the other hand, clients on Elitehost has not had any issues at all.
Anyone else been having a similar issue with xNeelo?
