How does MailWasher Pro bounce messages?

MailWasher Pro uses an algorithm to determine the best route to send the bounced message back (from, reply to, return path). MailWasher Pro can bounce a message one of two ways:

Local option - The bounce is sent back via your ISP's postmaster.

Remote option - The bounce is sent back via the sender's SMTP server.

You can choose which option to use by opening MailWasher Pro > Tools > Accounts > highlight account > Properties > Bouncing and outgoing mail > Advanced Account Options > Bouncing details.

In either case, the bounce looks exactly like it has come from your ISP and not from your address. If the spammer used a fake address, then your bounce message is itself bounced back to the postmaster (local option) or lost in cyber space (remote option) so you don't receive the bounced bounce email.
