We had been having some issues recently with our email server on this site, and were unable to send password reset or activation emails for a week or so. After wrestling with postfix for roughly two hours, I have restored our ability to send mail. Please note that any messages that were sent during these last few weeks may not arrive (or they may arrive all at once, I'm uncertain whether they were lost to the void). Hopefully there will not be any problems with our mail server in the future.
