error_soft (boolean, rw:rw)
Default: FALSE

Allow the '!' sign in the local part of e-mail addresses.

permit_percent_hack (boolean, rw:rw)
Default: FALSE

relay_check (boolean, rw:rw)
Default: TRUE
Enable/disable relay checking.

relay_domains (complex, rw:r)
Default:
Domains mails are accepted for. Use Postfix style lists. (E.g.: '.example.com' allows every subdomain of example.com, but not example.com. To match example.com use 'example.com'.)

Default:
Domains mails are accepted for based on a matcher (e.g.: RegexpFileMatcher).

Default:
Zorp zones that are relayed. The administrative hierarchy of the zone is also used.
