send-hook and signature

[Eugeny N Dzhurinsky <eugenydzh@xxxxxxxxxxxx>]

Hi, I have send-hook defined for some of mailing lists
For some of the lists the send-hook looks like
send-hook list@xxxxxxxx 'unset signature'

The problem I facing is the signature becomes unset for all lists as well as
for regular mail. The folder-hook didn't help :( What am i doing in a wrong
way?
