[Twisted-Python] Re: Help needed with SmartHostSMTPRelayingManager

[James Tanis]

Alright, I believe I answered my own question. I just need to override
relaymanager.SmartHostSMTPRelayingManager.__init__ and define
self.fArgs there to include the needed arguments.. correct? Just
wondering why this isn't included in the default __init__ if it's
required by the default SMTPClient.__init__
