Cpanel webhosting allows a "default address" to be set to forward all mail to. So the following is true.
email@example.com goes to firstname.lastname@example.org
email@example.com goes to firstname.lastname@example.org
email@example.com goes to firstname.lastname@example.org
This allows the flexibility to use *@domain.com whenever a disposable email is desired and at the same time enable checking all email from one account.
I wish to be able to reply to email sent to email@example.com without creating an account for it, such that I can simply reply from spam1 from my other mail account.
The reason I ask the question is that I currently import all my mail into a gmail account, and the gmail account can be configured to send mail as an address after the spam1 address has been verified. I want to move away from gmail and use my own hosting instead and at the same time be able to use this reply from the sent to address.
Currently availible I have horde, squirelmail and roundcube but am more than open to trying other webmail software thats installable over ssh jailed shell access or ftp. (Shared hosting)
