Is there an outage? My emails to two RR accounts are being returned with this error:

    host dnvrco-cmedge01.email.rr.com []

    SMTP error from remote mail server after end of data:

    552 5.2.0 ESMTP server not available AUP#I-1340

    A 552 email error is typically encountered when there is a problem related to an attachment in your email. Either it has exceeded the size limits of the remote server, or the file-type isn't allowed by the remote server.  Does your email contains attachments?

    Hello James, thank you for your reply.

    Yes, the emails did contain an iCalendar file attachment (bookings.ics.) I've sent them before so did something change?

    There have been no recent changes that I could locate.  The maximum size for email attachments is 25MB, reducing the email size should resolve the error message.
