On our BizTalk Server we have an error regarding received email messages with the POP3 adapter.The error message is "There was an authentication failure. "Failed to decode the S/MIME message. The S/MIME message may not be valid."BizTalk Server 2009, CU 2Configuration:- POP3 receive location- custom receive pipeline- apply MIME Decoding = true- basic authenticationIt seems it has something to do with the length of the header of the message. After installing CU2 for BizTalk 2009 I was able to receive messages with longer headers (more message receivers) but unfortunately we receive mails with even longer headers.I'll attach samples for working/ not working messages to this item.Thank you.
