This is an ancient quote, sorry if I've missed a more recent reference.
I'm getting these errors in paniclog, caused by messages submitted by an "black box" security monitoring device:
DKIM: signing failed: LONG_LINE
It seems I can't get the device to format its messages properly, so either some intermediary would have to reformat the messages, or perhaps exim could be made to work with this?
