Any chance to configure all domain to use amazon ses, except one domain and that domain should use another provider example postmarkapp? is that possible?

In theory that should be possible. You'll have to modify the Postfix main.cf file. But you'll have find out whether or not SES and Postmarkapp use conflicting settings. Also note that AWS SES requires all domains the be validated.

How you can configure Postfix for use with SES is explained in this article: Integrating Amazon SES with Postfix - Amazon Simple Email Service.

Then you'll have to make an exception for the domains to relay via postmarkapp. Which is descrived as multi-domain relay mapping in this article. Configuring Postfix for Multi-Domain Mail Relay
