SPAM with a large Word file on the side

Scott has provided us with a new piece of SPAM with the subject "Offshore Banking & Investment" with a 1Mb Word file attachment.  Having received two in 45 minutes, this is probably the tip of the iceberg, and as Scott mentions, will definitely start to load the mail servers.

If anybody else is seeing this, please let us know.  More data will be posted as it develops.....

Thanx Scott!

Probably an attempt to get around SpamAssassin. Emails with large attachments are commonly bypassed around it because of the CPU time it takes to scan them. 1 MB is a pretty common threshold because most spam is far under that size.
