If you have sent me email within the past few days you may have run into a bounce message. I have been able to track the problem down to the MailFoundry spam filter appliance at my hosting provider. The hosting provider attempted to fix the problem, but still ran into issues. They have a ticket open with MailFoundry. If things don’t get resolved within another day I’ll just disable the MailFoundry service on my account for a while.
Until this gets resolved, feel free to use my Gmail address miks2u-at-gmail.com to bypass the problem.
