I've been using the email to dropbox function pretty consistently for a few months now. Just today I noticed it doesn't seem to be working. I have an application setup to email invoices to my dropbox email for later processing. The emails I sent this morning did not hit my folder (but the emails and files did go out). I tested it by sending an email from my regular email and the file I attached again did not make it to my folder. I confirmed the dropbox email hasn't been changed and I don't see anything on the dropbox status page about this being an issue.
