Read this already, it doesnt seem there a DNS or relove issue - all works from telnet , thus resolved fine (also mial is not sending from both php mail() and roundcube to ANY adress except locally hosted ...

Just in case - as this is a VPS , and it got floating IP , i have TWO eth on system :

Code: [Select]

eth0      Link encap:Ethernet  HWaddr FA:16:3E:28:CF:D5
          inet addr:10.2.0.4  Bcast:10.2.0.255  Mask:255.255.255.0

          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

could this be an issue ?

The problem is you want send to remote but qmail think it's as local.

Some questions:
1. Your hostname is 'kampanj.viasat.se'. Is 'viasat.se' your owned and already exists in current server?
2. Are all domains using primary IP (10.x) as mail IP in DNS?
3. Did you send via webmail?

[BigWeb.EU]

Mustafa could you please remove the real domain name (change it to mydomain.xx) - i dont want it to be seen here Thanks

1. Your hostname is 'kampanj.mydomain.xx'.
YES

2. Is 'mydomain.xx' your owned and already exists in current server?
NO (this is just a subproject with own VPS)

3. Are all domains using primary IP (10.x) as mail IP in DNS?
NO - Are you talking about MX record?

4. Did you send via webmail?
NO PHP mail() sender

[MRatWork]

I am just taken hostname from sysinfo.

Try create website for kampanj.mydomain.xx in current server where add A record for 'kampanj.mydomain.xx', 'ns1.kampanj.mydomain.xx' and 'ns2.kampanj.mydomain.xx' also NS record for 'kampanj.mydomain.xx' in dns setting of 'mydomain.xx' (purpose: dns delegate kampanj.mydomain.xx to current server).

Try using primary IP as 'MX record' for all domains in current server.

This didnt work Another IP is a local IP, so its not external , and thus cant be used Maybe any other thoughts ?
