The WineHQ mailing lists were down today. There was a message in the queue that caused mailman to bomb. I found and removed the message (it was a spam). I also stayed in late and upgraded our Mailman to ver 2.0.13 from ver 2.0.0.
Let me notice if you notice anything unusual happening in the next few days.
Also, I am considering putting a SpamAssassin filter into our Mailman using info from this page: http://www.daa.com.au/~james/articles/mailman-spamassassin/
Anyone against this idea?
