How do I receive email sent to postmaster?
- by jonescb
I have a VPS server that I would like to get an SSL certificate for, and the CA needs an email address to verify that I own the domain. The options are: postermaster@mydomain.com, hostmaster@mydomain.com, webmaster@mydomain.com, and an address to @whoisguard.com.
The server runs CentOS 5, and all I have set up for email is sendmail. I don't have POP3 or IMAP. According to this Wikipedia article on Postmaster, it says that all SMTP servers support postmaster and it cites RFC 5321. Does sendmail conform to this? I tried sending a test mail to postermaster@mydomain.com, but I don't know how to receive it on my server. Do I need to open up any ports?
I haven't gotten a message back saying that my test mail failed to send, so my server must have gotten it.
