bbs.spamgourmet.com

I have emailed using SG addresses that I create. One recipient called me up and asked me why her Gmail is warning her about spam. She mentioned that an email from me will look like this in her gmail:

myusername.9a@xoxy.net via gourmet8.spamgourmet.com

I wish this "via" portion was not shown. How can we prevent this? Or can Spamgourmet.com prevent this from showing? My recipient thought I may be spamming her.

I use Spamgourmet.com for craigslist messages. And it's really awful if someone thinks you're spamming them when you're not.

I think that's something that gmail puts on there - we can't stop it from happening
