I've just set up a new SP list to log purchases made by our department. Whenever we buy something, we'll use the email address corresponding to a distribution group that contains myself and an Exchange contact for a list in SharePoint.
I've set the list to receive mail from any sender and preserve attachments. It's a Discussion list, because I want to keep both the contents and attachments. I tested it from Gmail and it worked as expected.
Now we've purchased some software. This purchase triggered five emails. The SharePoint list only received two of them. Looking in the logs, I have:
The file you are attempting to save or retrieve has been blocked from this Web site by the server administrators.<nativehr>0x800401e6</nativehr><nativestack></nativestack>
An error occurred while processing the incoming e-mail file C:\inetpub\mailroot\Drop\c49c754f01cd766d00000108.eml. The error was: The file you are attempting to save or retrieve has been blocked from this Web site by the server administrators..
To my knowledge, we've never had this issue before with email-enabled lists and we use them rather heavily. Two of the three messages blocked had no file attachments at all and were sent plaintext. All five came from the same source address. If the logs at least told me what file or filetype was being blocked, that might give me somewhere to start, but since it doesn't, and since SharePoint cheerfully tosses the .eml after processing, I don't really have much to go on.
The text of one of the email messages is as follows:
