hi
1 - i want to create a hash on an attachment of a pop3 mail, without
downloading the file itself.
is that possible?
is there any way to download a part of the attachment using the pop3
protocol? (like: "i want to receieve bytes 100 to 200 of attachment no
3 in message no 2).
2 - is it possible to forward a message from a pop3 account, including
the message's attachments - without downloading the attachments?
thanks.
This is a MIME GnuPG-signed message. If you see this text, it means that
your E-mail or Usenet software does not support MIME signed messages.
The Internet standard for MIME PGP messages, RFC 2015, was published in 1996.
To open this message correctly you will need to install E-mail or Usenet
software that supports modern Internet standards.

No. IMAP has an facility to provide the Content-MD5, but most messages do
not have this header so the Content-MD5 shows up as null.
There has not been substantial interest in this facility, even though it
can be useful to detect in-transit data corruption.

No. This is, however, a feature of the base protocol of IMAP.
I doubt that there will be any work to offer this in POP3.

No. This is, however, a feature of an extension to IMAP called URLAUTH in
conjunction with an extension to SMTP-submit called BURL. These are new
extensions -- they have been approved for publication as an RFC but are
not yet published RFCs -- and most servers don't have them yet. But in
the next couple of years these will become common since the mobile device
people need them.
I doubt that there will be any work to offer this in POP3.
