Hi, sorry that I missed your earlier message. I'm not familiar with smtp2go. I guess the possible bouncing reason is that either the smtp2go server or the Gmail server refuses this message because the message cannot pass their format validation.

As some issues discovered by espoofer have been fixed by some email vendors, you may want to try different test cases or try different email providers.

If you're testing in client mode, there is no need to have an SMTP server. Because espoofer works like a regular email client.

For server mode, I used a VPS server on Banwagonghost.com, which has port 25 open by default. Just follow the README instructions to configure and run espoofer on the VPS.
