User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; en-GB; rv:1.9.1) Gecko/20090624 Firefox/3.5 (.NET CLR 3.5.30729)
Build Identifier: version 2.0.0.22 (20090605)

When forwarding an email that has been send to you without (maybe with) being digitally signed, Outlook express reports that the message has been altered if digital signing is used for personal email authentication. Thunderbird does not see this as a problem and opens the document without any issues.

Reproducible: Always

Steps to Reproduce:
1.Take any received plain text email
2.Be sure that digital signing for person email identification is enabled
3.Forward the email to any mail address of a person with outlook express
Actual Results:  
Outlook express gives a black screen and says the email has been tampered with.

Expected Results:  
Outlook express gives a black screen and says the email has been tampered with.

Possibly removed the old header from the mail when forwarding to avoid verification problems.
No TB vulnerability here.  Sounds like an OE problem.
