Spam on Mailman lists

[David Gibson]

There was a (single) spam attack across a range of BCA's Mailman lists earlier today. (Including BCRA and CSCC lists; possibly more). This was a fairly "ordinary" spam attack and has been identified as being due to a particular loophole in the way the lists were configured. If anyone need further info in order to fix their BCA lists, please contact either myself or Dave Cooke.
