I have a list in my authorized to emails file as follows:


when i send an email to it should reject, right?
I can see in the log:
EmailTO is not in AuthorizedTOEmail list...

BUT when I follow the SMTP conversation the rejection comes later.
A typical SMTP conversation should by

mail from:<>
rcpt to:<>

however, what I am seeing is that after the 'rcpt to' i get 

which of course is not right.

Which of my settings is causing this?

The log shows:
01/16/12 00:48:53:513 -- (2244) Detected TCP Connection:
01/16/12 00:48:53:513 -- (2244) Connection from:  -  Originating country : United States
01/16/12 00:48:53:700 -- (2244) Received MAIL FROM: <>
01/16/12 00:48:53:778 -- (2244) Received RCPT TO:
01/16/12 00:48:53:794 -- (2244) - EmailTO is not in AuthorizedTOEmail list...
01/16/12 00:48:53:794 -- (2244) - Mail from: To: will be rejected
01/16/12 00:48:54:403 -- (2244) Start virus scan
01/16/12 00:48:54:450 -- (2244) Starting bayesian procedures
01/16/12 00:48:54:544 -- (2244) Blacklist cache - Added to limbo
01/16/12 00:48:54:778 -- (2244) SFDB - Added - Response: Error=0
01/16/12 00:48:54:778 -- (2244) Disconnect

I'd like Spamfilter, to disconnect the session when the recipient is invalid (assuming it's the only invalid recipient in the rcpt to list)

Thanks in advance for your pointers.

The spamfilter version I am

Hi ImInAfrica,

I think the setting you're looking for is this one in the SpamFilter.ini file:

;If the "AuthorizedTO" whitelist is used to specify the list of valid email addresses that can be accepted, by default SpamFilter will terminate a connection when the remote server specifies an invalid address in the RCPT TO command. You can use the following option to disable this forced disconnect, and cause SpamFilter to simply reject the invalid recipient, and continue to accept additional ones


which was probably changed to "false" at one point. Please do let us know if it was already set to "true" so we can look into this more.

Hi Roberto,
I had this setting set as follows

I've changed it to true and will test, though i suppose =1 or =true is the same.
