>1. Are only attachments sent thru web messaging being put in the Spool

>from?
Only web messaging attachments are placed directly in the spool
directory. Regular E-mail will appear in the spool directory, but the
whole E-mail with all the attachments will be encoded into one file that
the virus scanner won't be able to scan (because of the encoding).
>2. Where are attachements opening? On the server or on the PC?
With web messaging, IMail decodes the attachment(s) and saves them to the
hard drive (or encodes uploaded attachments for outgoing E-mails). The
files are uploaded/downloaded from/to the client's PC.
With standard E-mail (SMTP/POP3/IMAP), the attachments never exist on the
server except in the encoded format in the original raw E-mail file (first
in the spool directory, then in the user's mailbox in almost exactly the
same format).
>3. Why is it important or not important to put a virus scanner on our
>Imail server?
There are usually two reasons: [1] To protect the mail server itself from
being infected (although this is usually rare, if the mail server isn't
used for day-to-day operations), and [2] To protect users from
sending/receiving viruses.
For #2, you need to use software that is capable of decoding attachments,
such as our Declude software, or McAfee's WebShield SMTP.
>4. From what I understand, most ISP do not scan the mail for virus's before
>they are passed down to the PC.
Lots do, and lots don't, for many different reasons. The same holds true
with other types of businesses (corporations where mail only goes to/from
their employees, schools, and so forth).
