hi all in the admin menu i whitelisted an ip but still i get this:

postfix/smtpd[13650]: warning: hostname blabla.somednshostname.com does not resolve to address 123.123.123.123
Feb 20 12:01:44 sf02 postfix/smtpd[13650]: connect from unknown[123.123.123.123]

so i whitelisted the ip 123.123.123.123 but still it gets rejected. How can i whitelist an ip so it can always send email?
 
Where did you whitelist the ip?
You need to add it to the mailproxy whitelist: Configuration->Mail Proxy->Whitelist

I hope that helps!
 
Glad that was the resolution - please mark the thread as 'SOLVED'

Thanks!
 
hey there still seems to be not working just checked and i still see:

Feb 20 15:12:40 sf01 postfix/smtpd[7779]: warning: hostname static.somedomain.net does not resolve to address 123.123.123.123: Name or service not known
Feb 20 15:12:40 sf01 postfix/smtpd[7779]: connect from unknown[123.123.123.123]

changed the dns and ip due to privacy.
ive added, the ip, domain from where its being send and the hostname too all 3 yet i still see this in my logs.
 
do the mails pass? (I would expect so)
The message indicates that there is a DNS-problem for static.somedomain.net - but should not prevent the mail from being accepted (since the ip is whitelisted)
 
seems to work now. Just adding one is fine? like mail adres or ip etc.. right? as i have it added all 3 now what seems overkill.
Also appeared to take a bit is this possible?

I think you need to add either IP or hostname (since it fails the check at that level (because you have enabled 'Reject unknown clients' or 'Reject unknown Senders' in the mailproxy options))

what took a bit? the whitelist to take effect? usually this is instant - if you have a cluster it can take up to 2 minutes for the sync to run.

I hope this helps!
