Removing Unchecked tag

[tenchimuyou]

Hello!

My client needs to send some password protected zip files, but he needs that the messages arrive without the "*** Unchecked ***" tags on it. How can I do that? I've tried modifying the amavisd.conf.in file and setting $undecipherable_subject_tag = undef; but when I restarted the mta, its took ages and did nothing. Nothing is being shown on logs, and if I press control-c, the mta starts without failures, but messages stopped arriving.

Any ideias?

Thanks,
