I have a MOSS 2007 HU 64bit, Win2008HU 64bit with sp and patch.DucomentStore is configured for recieving email. It works, saves email's body and attachment into the documentstore.But if it recieves an email with (locally root) CA digitally signature (smime.p7s), then it saves only the email's body, attachment is lost. What is the problem?Thank you.fs

Hi, do you try the same attachment from same client without digital signature? Check this KB: http://support.microsoft.com/default.aspx?scid=kb;en-us;926891 for encoding of emails. Check that the Root CA Public Certificate are in the MOSS Server Certification store named "Trusted Root Certification Authorities" Bye. Raffa!!!

Yes, "It works, saves email's body and attachment into the documentstore. But if it recieves an email with (locally root) CA digitally signature (smime.p7s), then it saves only the email's body, attachment is lost. " , and the Certificate is in the store. fs
