I use the mail proxy from bordermanager 3.8
My question is: Is it possible to disable the following Anti-SPAM-feature.

Does not allow mail relay from Mail Proxy primary domain (impersonating
domain). It checks for the IP address that is generatin e-mail and compares
it to the internal mail server. If they are different the proxy errors
out with <554 transaction failed>.

Is it possible to overwrite this feature with an access rule wich allow
such mails? Are there some comandlineswitches for Proxy.NLM? Are there
some settings for PROXY.cfg.

Thanks in advance
