-----END PGP PUBLIC KEY BLOCK-----

My key can also be found on most key servers. In general I sign all outgoing mail with my PGP key but will only encrypt a message when either responding to an encrypted message or handling sensitive information.

Attachments

Broadly I divide attachments up into three categories:

The good
Open or ISO standardised formats such as plain-text, PNG, JPEG, OpenDocument and PDF.
The bad
Proprietary formats with good support from open-source software. Classic Microsoft Office formats such as .doc and .xls fall under this category.
The ugly
Proprietary formats with poor or non-existent support from open-source software. The new Office Open XML formats (.docx, .xlsx, …) fall in this category.

Although I have no objection to receiving attachments in the second or third categories I do not make any guarantees about being able to open/view them. Therefore, it is advisable that if you do send an attachment in one of these categories that you also attach it as either plain-text or PDF.
