What’s new with Mimecast?
With Mimecast, our new email management tool, you may see a few new emails and other various changes. In this document, you will see these changes, what they mean, and what to do should you come across one.
With a new tool, comes a new postmaster. If you should receive an email from Domain postMaster address and it DOES NOT have our yellow Suspicious From field header, then it is from Mimecast.
The one major change you will see within emails is that all attachments received with a size of 25 Megabytes (MB) or over have been replaced with a link. This will help keep your inbox from having to hang onto attachments that would otherwise needlessly take up space, while allowing for you to access the attachment. Below is an example of the linked attachment.
Mimecast will scan emails before allowing them to be sent or received, searching for anything malicious or blocked by Gold Star Financial’ attachment policies. In such a case, the attachment will be removed with a brief message stating that the attachment had been removed, as seen in the example below.
Emails that end up bouncing back to you will also look different, giving more details as to why it had been bounced back. This will be sent if your initial email cannot be successfully sent, as such in the example below, the email address we tried to reach was misspelled.
Messages on Hold
Some emails you may send or receive may be held by Mimecast if it is determined to be possibly malicious. While it may be flagged as such, there is also the chance that it will be flagged by accident. For example, if an excel spreadsheet that you have used as a template has office macros within it, it may be held due to those macros. An example of such an email is located below, along with an explanation of what to do.
Reach out to firstname.lastname@example.org if you should receive this email and believe it to be in error.
