Hi,
I have setup postfix to receive mail on port 25 and I am getting mail fine from my ISP. Now I'm setting up fetchmail to grab mail from another account using POP3.
Fetchmail grabs the mail from the account fine and sends it to the SMTP port where postfix accepts it fine.
The problem I have is that the mail never hits my mailbox. When I look at the logs I can see it's trying (correctly?) to send mail to dave@localhost.my.domain.com but it can't resolve localhost.my.domain.com to my linux box.
My resolv.conf points at my router (which presumably forwards requests to my ISPs DNS servers.
Do I need to set up DNS on my linux box or is there a simpler way I can do this??

Second question - How (and What) do I need to configre to allow the sending of mail from my linux box (ether via my pop3 account which provides SMTP for outgoing mail or my ISP smtp account)

Thanks for your help
Dave

On the first question, You can add localhost.my.domain.com to the 127.0.0.1 address in your /etc/hosts file. You will also have to add the same name into the postfix main.cf file on the 'mydestination' line and then reload postfix.

For the second, you really should have DNS configured to send mail out (unless you simply want to pass all of the messages to your ISP for actual delivery) so that your IP address is resolvable (the ISP can do that). If you simply want to pass the message to another system for real delivery, simply set the 'relayhost' parameter in the main.cf file and postfix will send any non-local message to that system for delivery.

Excellent, I'll try that when I get home tonight. I'm not quite sure I'm ready to set up DNS yet. Once I have fetchmail working my next mission is apache and webmail (probably Squirell Mail)
Thanks
Dave
