Virtual postfix sending problem

[generalchaos]

It seems like when im sending mail out that it is always going to root@localhost.localhost , any ideas why? This is making all of my servers website scripts not be able to mail the users it needs to send mail to.

even if I just type "echo "test" | mail myemail@comcast.net" it sends it to root@localhost.localhost

What's in your mail og when you try to send an email?
What's in /etc/postfix/main.cf (please strip out the comments)?
What's in /etc/aliases?

heres what my maillog shows when I do something that requires mail being sent.

Jul 12 12:37:36 localhost postfix/pickup[22519]: A945F250326: uid=502 from=<apache>

Jul 12 12:37:37 localhost postfix/cleanup[22559]: 37C9B250328: message-id=<20060712163737.37C9B250328@localhost>

Jul 12 12:37:37 localhost postfix/qmgr[22520]: 37C9B250328: removed


So it looks like either something changed with a comcast setup (even though it always worked before) or its not liking the fact that the email is coming from apache@localhost.localhost ?

[generalchaos]

After looking around some more and doing a dnsreport, the problem is the "myhostname = localhost" ...I don't know what to do about this though. If I set the hostname to one of my domains, it will send email fine (however the from field is blank in the email)

but I have multiple domains.

[falko]

You must change

myhostname = localhost in /etc/postfix/main.cf. Use a real domain/FQDN here that's on your server. Restart Postfix afterwards.

[generalchaos]

well, thats what im doing right now, but im using no-ip for my domains so its not actually on my server.

It works fine if I email from the domain that I wrote in there, but if i use my other sites the emails come from "(unknown)".

[falko]

You can use one of your no-ip domains for myhostname.
