If you get an e-mail with an attachment of a PDF with hints of having to change your e-mail settings, don’t open it as it has a virus payload.
Here is a good writeup on how it works for those that are curious:

We will be adding additional storage capacity to our mail server this weekend. There will be some minimal outages lasting just a few minutes at a time while we move to using the new storage from the old storage. Mail will continue to be received during the upgrade but may be slightly delayed during the weekend. Everything should be running smoothly by Monday.
Thanks -
