You have to feel concerned about a company that touts its e-mail security cred but only has the most rudimentary web interface, no apparent signature collection ability, and lets through glaringly obvious phishing e-mails. I get "Hey we quarantined some Viagra spam" notifications every few days, while dealing with unwanted stuff from less obvious sources. For this we gave up a company that offered whitelisting, blacklisting and everything we could want in between.
