About a month ago Softlayer (without any notice or warning) blocked all outgoing port 25 at multipole datacentres for this provider. It took the hosting provider half a day to work out what had happened. Needless to say as much as I liked the company I had to move my hosts elsewhere (they did refund me to their credit). It seems that someone at Softlayer is extremely aggressive on their blocking policies to the point of making their service unusable. I would highly recommend the community votes with its wallet when it comes to these turkeys.

The announcement supposedly came out sometime late last year.
"We offer a trusted third party email relay service from SendGrid for
those customers who need to be able to send outbound email from their
domains or applications."

It seems some indirect customers were not informed of it until it went
into effect on Feb 1, 2016. For me the monitoring service on port 25
stopped working.
