# Return path

Also called: MAIL FROM, envelope sender, bounce address

The hidden address that bounces go back to, separate from the From address people see. SPF is checked against its domain.

## How this affects you

Every Vaartix domain's return path is `vxmail.yourdomain` (or `vx-bounces.yourdomain` on older domains, and when `vxmail` already receives email). Gmail shows it as "mailed-by" under "Show details". It has to be a subdomain: Amazon SES requires it, and an MX record on your main domain would take over its inbox. Until its MX and SPF records pass, email still goes out, but shows "mailed-by amazonses.com".
