I don’t see a way to exclude certain types or sources of mail sent by the site. For example, every system e-mail generated to my admin address is, stored, logged and tracked by this plugin. It just needlessly bloats the database. (every password reset, comment posting, and such is tracked. This is mail to ME, not really from the site to the general public.) If I could filter out e-mails to my WordPress admin address, that would be a big help.

Another use case are e-mails generated by a contact form. These aren’t mails to other users or the general public, they are mail sent TO me as the site admin via the form. (or TO other relevant site personnel) This results in contact form spam filling up my db via this plugin. I have other ways to handle the contact form spam, but like the system messages, I don’t need contact form messages stored, logged and tracked.

Thanks! And I otherwise really do like the plugin. It is especially useful for e-commerce to see/prove that customers are reading their cart communications.
