Well that's a hassle

I took a glance in the spam folder on my Gmail account this morning and discovered two things: First, the SMTP server I use for handling my outgoing email has been blacklisted as a spam server. Second, that Gmail's spam filters think that the "that server has been blocked" messages are, of course, spam. I'm curious to know how many of my job applications and roommate inquiries in the past few months have gone silently into the bitbucket without ever being seen by human eyes.
