# zmtrainsa <user@domain> ham Inbox
mktemp: cannot make temp dir spam.XXXXX: Invalid argument

To fix this, change line 65 in zmtrainsa
From:
tempdir=`mktemp -d -t ham.XXXXX` || exit 1
To:
tempdir=`mktemp -d -t ham.XXXXXX` || exit 1

PS. Spam training works fine, mktemp seems to require a 6-char tmp extension (at least on my Ububtu)
