550 5.7.1 Recipient not authorized

[Daxel]

I am trying out your product, but when it goes to get the email from one particular account and forward it, it encounters an error:
Server rejected message: 550 5.7.1 Recipient not authorized, your IP has been found on a block list

which related to the entry log in Exchange as follows:
Timestamp       : 1/6/2009 11:54:13 PM
SessionId       : 08CB3CE309A01D1B
IPAddress       : (removed for privacy)
MessageId       :
P1FromAddress   : (removed for privacy)
P2FromAddresses : (removed for privacy)
Recipients      : (removed for privacy)
Agent           : Connection Filtering Agent
Event           : OnEndOfHeaders
Action          : RejectMessage
SmtpResponse    : 550 5.7.1 Recipient not authorized, your IP has been found on
                   a block list
Reason          : BlockListProvider
ReasonData      : zen.spamhaus.org

Which would make sense, because the first message in the remote mailbox is from a location blocked by zen.spamhaus.org.
However, the issue I have is that with that first message failure, your application stops forwarding any of the OTHER mail, instead of bypassing the first one.

Is there a workaround?

Hello,

in the latest PopGrabber Standard version, it is possible to configure what action to take when the Server rejects a message. This has not been yet implemented in the free version but it will be in a couple of days. We will let you know as soon as we release the update (probably tomorrow).

Hello,

the PopGrabber Free version has been updated and it is now possible to skip or delete (with optional backup) messages rejected by the server.

Let us know if this works as you expected.
