Bandwidth overview reports show consumption for SMTP (in and out), IMAP and POP. But there is no accounting for EAS, EWS/MAPI or Webmail.
We're adding a big new account and bandwidth has soared by a factor of 50x-- from a few Mbps to upwards of 100 Mbps during the workday hours-- but SmarterMail reports aren't reflecting it in the SMTP, IMAP or POP numbers. Seems EAS/mobile and Webmail are the most likely culprits, since almost none of their users are on Outlook.
Requesting EAS, EWS/MAPI, and Webmail (we use IIS) bandwidth consumption to be included in the Bandwidth accounting in SmarterMail, to give us a MUCH better picture of how SmarterMail is consuming network resources.
