*** Only outgoing email traffic to recipient's mail server that applied SPF checking will be affected ***

Service Disruption Details:
As default our shared hosting SPF record is using the following:

v=spf1 include:spf.mschosting.com -all

This SPF record consists of all Exabytes shared hosting IP addresses and when there is a new IP range, we will modify on spf.mschosting.com

Our team find out spf.mschosting.com DNS entry corrupted this morning and our team is working on it.

Service Disruption Affects:
During the service disruption period, all outgoing email traffic will get a SPF checking failure status to recipient's mail server that applied SPF checking.

Sample of bounce back email message which carried the same meaning from different type of mail servers:

520 ip and spf record not match

550 Message rejected because SPF check failed

550 rejecting for sender policy framework

5.7.1 Rejected due to SPF policy for sender
