Dear All, The issue with the HKL2000 e-mails seems to have been caused by the request for an acknowledgement of receipt of the e-mail, coupled with clients at Buffalo acknowledging the receipt back to the list. The current situation is that these e-mails (some 7000) have been deleted from the queues on the daresbury mail servers (which were taken off line to deal with the problem), and that the mail server at buffalo has been temporarily blacklisted to prevent more messages being sent. Hopefully this particular problem has been resolved.
Sorry for any inconvenience, Charles Ballard CCP4 Ps - can people try and ensure that they do not ask for acknowledgements of receipt on e-mails sent to CCP4BB.
