We’ve added two new features: a “new” method for the API “mailbox” method so you can create new hosted mail box accounts through the API and a unique “Trim Message (DATA) Size To” to our mail services.
The “Trim Message (DATA) Size To” advanced option was added per request. It’s unique in that it allows you to set a hard size limit for incoming mail that our system will trim (truncate) to instead of rejecting large messages. It will break attachments and multipart messages that exceed the limit, but the untrimmed part of the message will still make it through. Mail mirroring and forwarding are not affected by the trim – only SMTP destinations.
