The short, nontechnical answer is that your mail software, either Microsoft Outlook or the behind-standing Microsoft Express mailserver, is unable to deliver to you a standards and RFC compliant ASCII plaintext e-mail message which would be sent from Linux users and has instead tried to convert it into something cooked up by Microsoft. Your mailheaders:
>X-MimeOLE: Produced By Microsoft MimeOLE V5.00.2615.200
>Content-Transfer-Encoding: 8bit
>X-MIME-Autoconverted: from quoted-printable to 8bit by id
may give some clue about what is happening in the mailserver on your network. The answer may be as simple as asking your mail administrator to specify a new PGP MIME type or allow the passage of plaintext e-mail unfettered. Or you may have to ask your Linux correspondents to send their PGP mail to you in some special way, i.e., as an attachment, gzipped, quoted-printable, etc. Dwight -- Dwight Johnson -- Archive is at - Unsubscribe by sending mail with a subject of "unsubscribe" to
