vMailias makes it easy to generate unique redundant email addresses for web-site registration.

If you have your own domain, with a catch-all email account, you can use vMailias to quickly provide unique email addresses for your catch-all account when registering with web-sites.

If you have a Gmail account, vMailias can perform the same service, using the Gmail '+' notation to generate email addresses that are directed into your main Gmail account.

Tracking which email address was used for which web-site also makes it easy to set up rules to guide email from different web-sites into their own folders, and to easily identify the source of spam, and filter it out.
