I have diagnosed to this to where maybe it can be debugged. The email in question includes one line with the following text: .......
That is, my correspondent wrote a line with 7 periods in it. When I download the message using a POP server, the line comes through with the 7 periods, and the signature is just fine. When I download the message using the Webmail extension, the line comes through with only 6 periods. The Webmail extension loses one of the periods somehow. Because the Webmail extension has essentially tampered with the body of the message (by removing a period), Thunderbird detects that fact (because the signature is wrong) and reports that to me.
