Richard, Deliveries are now flowing quickly again. I noticed an old and orphaned .pck file in the qfiles/in directory and deleted it (the system had been halted using reboot earlier in the day which may have caused this). But I didn't see any errors related to this file in the logs or on the console. Next time I will see what the qrunner -v option tells me ;-) BTW Is the in/queue processing always FIFO in Mailman 2.1?
