Please don't obfuscate web1_hosam@server1.example.com

There's a problem with example.com, but you're not the owner of that domain. If you want help, please provide all required info. What's in the mail log?

I'm a bit surprised. This mail log is dated January 2nd, So thats 2 months old. Are you sure this reflects your session?

Also, This mail log does not look like a maillog of a system setup according to the Perfect Setup guides.Jan 2 00:25:34 php1 postfix/smtpd[9068]: warning: support for restriction "check_relay_domains" will be removed from Postfix; use "reject_unauth_destination" insteadis a custom entry.Mar 12 20:01:13 php1 freshclam[8307]: Received signal: wake upFreshclam is normally not run this way, and it certainly should not log messages in your maillog. The fact that Yahoo reject your message is because rDNS is not setup correctly. According to these logs, your sending IP address is 82.129.141.246. dig -x 82.129.141.246

Let's start with the beginning: Is this truly the log file of the session you tried and which failed?

[EL7oot]

i think the problem is with hostname

[falko]

You must create a DNS record for php1.amwag.com.eg. Currently, it doesn't exist:

mh1:~# dig php1.amwag.com.eg

but i don't know how 2 creat a dns record so,

tell me plz

thx for replay FALKO

[till]

Either you ask the company where you registered amwag.com.eg to create the record for you or if they offer a admin interface for this, create a A-Record for php1.amwag.com.eg that points to your server IP address.

It may take up to 48 hours until the DNS change becomes valid.
