Why do I receive multiple Quarantine Reminder e-mails?

There are at least two reasons why you may receive multiple Quarantine Reminder e-mails:

  1. If you mailbox has multiple e-mail addresses associated with it. Please see Mailguard - How to merge user accounts for information on to merge multiple Mailguard accounts in to a single account.
  2. If you also receive e-mail for a "role" account.  To prevent all of the members of a role account from receiving Quarantine Reminder e-mails for the role account, merge the Mailguard account for the role account in to one user's Mailguard account.  That user alone will then receive information on quarantined e-mails for the role account.

Q: What is the maximum e-mail attachment size?

A: The ETRN.com e-mail servers do not limit the size of individual e-mail attachments. The ETRN.com e-mail servers do impose a 400 MB maximum total message size limit. Individual customers can choose a smaller message size limit. We can also customize the handling of "over-sized" e-mails. Please contact us to discuss your specific needs. A couple of important facts:

1. Attachments are typically encoded in what is called Base64[1]. As a result, the actual length of MIME-compliant Base64-encoded binary data is usually about 137% of the original file size.

2. E-mails often contain both plain text and HTML components. This also increases the overall size of the e-mail.
