Hi Richard. You may have your SM set to use the IP of the machine or a certain IP and not the IP of the domains. Log into your SM admin interface and click on Settings then Protocols. Look to the right under SMTP OUT. Make sure you have Use the Domain's IP selected instead of one particular IP. This will resolve your issue. Thanks!

Hello Linda thanks for pointing that out.

Do I have to set all 400 domains manually to use the main IP so I can set the few other domains a different outbound IP?

because all domains do not have an IP specified now

how will that work?

 

I thought that the IP number set with the domain will overrule the main server setting.

ok.. I dared to fiddle around with the IP settings
I have set: use the domain IP with the server setting and Use main IP number of server if no IP is set. So most domains will mail out via the main IP number.

 

Still, why have the option enabled to select an IP on domain level if it's fixed on server level and choosing something else on domain level doesn't matter.

 

wouldn't it be logical if the setting on domain level would overrule the server setting?
