Mailer intercepts emails sent from your blog, stores them on disk and delivers them slowly to never hit the provider limits and risk a ban.

Mailer is compatible with WordPress and every plugin that use the wp_mail() function.

Some features:

• configurable delivering speed
• alternative sender email and name settings
• SMTP ready
• email grouping (extension for 3rd party plugins)
• email priority (extension for 3rd party plugins)
