Mailshell users can compose email from any email service and have it sent from a disposable Mailshell address by using a special "to" address format: to-name.at.to-domain@from-name.at.from-domain.

Replying to email received at a forwarding addresses or through IMAP automatically formats the "to" address as described above.
