Pretty sure the following contraption in the postinst script is responsible:
36 echo "$RET" | sed -r -e ':a s/(\[[^]:]*):/\1=/; ta' \
37 -e
's/[[:space:]]*:[[:space:]]*/\n/g' \
38 -e ':b s/(\[[^]=]*)=/\1:/; tb' \
39 -e 's/[][]//g' >
/etc/nullmailer/remotes
Unfortunately I am not completely sure what happens here (and what could possibly removed or fixed).
