Just purchased this addon as people kept having trouble with our contact form, continually trying to upload larger then the stated limit allowed and then would contact us to figure it out. So we bumped the allowable sizes and added this plugin as backup if the email was to large to send via email. Worked as easy as 1,2,3!! No configuring or anything, just activate and relax. Sent two tests and both showed up with the extra-large attachements no problem!
Thank you very much!
