Problems with outgoing apache mails

[jep]

Hi,

One of my clients asked me why he doesn't receive mails from apache. When i look in the logfile, I get:

2003-12-15 23:09:44 1AW0uN-0006dP-Vb ** XxXxx@wxs.nl R=lookuphost T=remote_smtp: SMTP error from remote mailer after MAIL FROM:<apache@server1.XXrio.nl> SIZE=1872: host mail.wxs.nl [195.121.6.51]: 550 5.1.8 invalid/host-not-in-DNS return address not allowed

What's wrong?

Hello,

1) does your hostname resolve
2) do you have a reverse IP lookup on your server IP
3) does the senders domain resolve and have an MX record

check out www.dnsreport.com for info.

The domain server1.domain.nl didn't resolv. :p

I made an A-record, so I hope that it helps. Thanks!
