Hi, all

  I'm using qmail-ldap with maildrop.  I set the mail forwarding by .mailfilter like this :   cat .mailfilter cc "! chen...@gmail.com "   when I sent the mail from sohu.com to <URL:mailto:chen...@east.net><URL:mailto:chen...@east.net&nbsp;mailto:che ngl...@east.net>chen...@east.net . the <URL:mailto:chen...@east.net>chen...@east.net is forwaring the mail to <URL:mailto:chen...@gmail.com>chen...@gmail.com using .mailfilter file above the log shows:
