So what you're saying is to send the emails in batches of no more than 15, wait about 30 seconds and go on?

Rafael,

When sending through Google mail servers, I have found the following
prevents issues with the servers shutting the account down for the day.
     sending 15 emails during a single connection
     pause 200 milliseconds between each email in the connection
     wait 5 seconds before reconnecting

Different providers require finessing, so these are something the user can
adjust in my software.

HTH,
Tracy
