Did you try use a nails.options file as discussed in the product readme its (inside the download zip also posted here
See silent install section In this you can specify the smtpserver IP address.
Thanks for the reply.
I'm pretty sure that your sugestion will work. But my problem is that when I deploy a package from the epo server, the wrong smtp server is used.
I would like an IP address inside the nails.options that get pushed directly from the epo server itselfs , in that case my auto deployment will not fail anymore.
I think this is a bug from McAfee itself.
