My understanding is that a digital signature often consists of a checksum encrypted with the sender's private key which the recipient can verify with the sender's public key. Is that what XMITIP does? What CA does it consult for the keys? Is EBCDIC a problem? (And why do my most trivial emails nowadays have at least 5KB of crap headers? Is that a signature added by the sender's SMTP and verified by my IMAP?) -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
