/usr/var/spool/mqueue suddenly increasing in size could have
indicated a spam relay in action, but the mail log show the following
error repeatedly occurring:
Mar 6 11:50:00 yoda sendmail[11087]: k26Bo050000011087: from=root,
size=53, cla
ss=0, nrcpts=1,

Mar 6 11:50:00 yoda sendmail[2718]: k26Bo0R0000002718: SYSERR(root):
Cannot bin

which is caused by an error in the NIS config.
Thanks again for all replies.
