## Description

Send mail using SMTP without exceeding the the rate allowed by your mail provider(
s). Mail can be sent using multiple
 user logins/passwords to give fault tolerance
and make each mail message somewhat unique so that it is less likely to be flagged
as SPAM/UCE by either your or the downstream mail providers. Messages can be automatically
resent when the plugin detects Non-delivery messages (NDRs) returned from mail sent
by the plugin.

Email can be throttled per outbound SMTP account. Limits can be set for maximum 
number of recipients per hour and per day.

#### Features

 * Sends mail via SMTP
 * Send mail no faster than the configured number of recipients per hour and day.
   Keeps you in complience with your providers email sending limits.
 * Configure multiple SMTP accounts to use for sending messages (Gmail, MSN, Go-
   daddy, etc)
 * Process non-delivery messages and automatically resend messages
 * Keep record of sent mail messages so that you can prove to your provider you 
   didn’t send SPAM
 * Automatically stops sending email when errors encountered, auotmatically restarts
   after configured period of time
 * Mail sending statistics display

#### Benefits

 * Using multiple email accounts makes it less likely that your email will be incorrectly
   flagged as SPAM by downstream providers
 * Use in combination with other email newsletter, sending and formatting WordPress
   plug-ins
 * Reduces non-delivered mail due to invalid SPAM flagging or exceeding near or 
   downstream provider sending/receiving limits

### Notes

#### Non-Delivery Processing

Non-Delivery (NDR) messaging processing note: plugin should recognize common non-
delivery formats. But, because non-deliveries are free form, and can be highly customized
or specifically localized the plugin may not recognize the message. If you provide
a sample non-delivery message we can make the plug-in a little smarter.

  How are non-delivery messages retrieved?

mailbox to forward any messages received to that single mailbox. The plug-in accesses
that mailbox using the POP3 protocol. User name a password for the POP3 mailbox 
are configured in the settings page.
