I have a problem with the sendmail program. I am using Fedora 6 and am still a newbie. I recently wrote a small code in PHP to test an email form.The problem i have is that i only can send email to people on my network.
The server i am using is not the mail server. We have a dedicated mail server.
An example : Just say my mail sever is mail.pointflex.net, i only can send emails to addresses like email@example.com,firstname.lastname@example.org but i cant send emails to email@example.com,firstname.lastname@example.org.
I guess this has something to do with configuring sendmail or i could be wrong.
Watever it is i need some help, any kind of help. So can someone guide me please...
I really need some guidance as i am a newbie to fedora and sendmail configuration is a daunting tasks for newbies. I wish fedora can come up with a simpler way to configure sendmail.
There could be a number of problems:
- The DNS server configured in the /etc/resolv.conf file may not be configured as a caching DNS server that relays Internet domain information to its clients. It may be just an authoritative server for the pointflex.net domain.
- Your server may not have access to the Internet on the TCP mail port 25, thus preventing the sending of mail to domains external to pointflex.net.
- Your sendmail configuration /etc/mail/sendmail.mc may require a correct SMART_HOST entry (if you are using a mail relay server for your network)
