josh, I'd take a minor issue with what you said. Banks (and anyone else) should not be assuming that emails are in any way secure, unless their content is protected by decent encryption: and then you can only say the content is secure. Emails can be deleted, copied, or modified in transit. If anything, they are less secure than a message written on a postcard. (I know you know this, but it is well to point out to people occasionally.)
The banks I deal with have supposedly secure messaging systems integrated into their online/Internet Banking websites and take great pains to tell customers that common-or-garden emails are not to be used for confidential information e.g. do not send your bank card PIN in an email.
Spamgourmet is not changing the security profile of email in any meaningful way (although if people are sensitive about the NSA taking copies of emails, non-US citizens resident outside the USA may have reservations about sending their emails via your servers that are on US territory. Shrug. You do not hide the fact you are a US-based service, so if people don't like it, they don't have to use your service.)
