using an email server from an external domain
I have a slackware machine which has preinstalled the sendmail mail server. For this machine I have given a domain name (I have a static IP), so I'm able to administer my email through the UI of webmin, i.e. I can send and receive emails.
However I would like to use it only as an email server, i.e. what I would like to do is
- Conecting to it, by using an email client (e.g. Thundirbird) in order to receive and send emails
- Conecting to it from a web server so a to send new posts etc.
By searching around I found that in order to test the mail server from outside you can use the following series of commands:
However in rcpt to: I receive an error "Relaying denied".
telnet mydomain 25
Here is also the DNS configuration
Any ideas, or how I could configure the email server?
Name Mode Value Priority
domainname A myip 0
*.domainname A myip 0
mail.domainname MX myip 1
Thanks in advance
