Other mails from the application are sent correct so they also don't show up in the maillog. And also the problem is I don't know what 172.30.2.13.

Also another question about this situation. As you can see in the log the host can't be found where is refered to DSN. Isn't that a mistype for DNS?

The company answered that 172.30.2.13 is an SMTP Relay Server. But the strange thing is that all the other mails sent from that application also use that SMTP Relay Server and that works fine...

So are you only having problems with one specific domain name or several?

In that case it may be that sendmail is configured to send all mail to the relay server without using the local name resolution system. This config is described here.

DSN is "delivery service notification".

These informations suggest it is the relay server that is generating the error message in the OP.

Are you able to find an MX record for isioux.nl using your DNS servers?

EDIT: I can:
Code:
c@CW8:~/d$ dig mx isioux.nl

; <<>> DiG 9.4-ESV-R5-P1 <<>> mx isioux.nl

The mail isn't send through or own mailservers. The application is also hosted on another server outside our network. So it has nothing to do with our mailserver. That works fine.

It is maybe a stupid question but wouldn't it solve the problem by adding the name server to resolve.conf? e.g. adding 172.30.2.113 to that file?

If my analysis of the error messages is correct it would not make any difference -- so it is a good test!

Ok again

In the past a manage-application is build for a company which has to send mails triggered by a cronjob. There are several different mails that are send from the application, each type triggered by a (different) cronjob of course

So let's say we have mail A with content A and mail B with content B. Mail A is sent to users C, D, E and F and mail B is sent to users G, H, I and J.

The system is able to send mail A but not to send mail B. Both mails are send through the SMTP Relay server (172.30.2.13 in this case), also the mails are sent directly to the recipients. How can this be solved? All necessary data I provided already earlier posts in this topic

This is from the maillog that won't sent the mail

Ok, so we know already the issue host not found etc. bladieblaat So is there maybe somebody who know's when and where is determined to use 172.30.2.13 as the name server is 172.30.2.40 from what I know... Or am I now just confusing 2 different things...
