Hi Timo Sirainen, It?s working with me fine. With no problem. After I configured my MTA (sendmail) to run dovecot-lda as root with chmod 4750 /local/user/libexce/dovecot/dovecot-lda. And create group called secmail. I had to change dovecot-lda group to secmail. And then added mail to secmail group. It works with me. Before when I changed dovecot-lda group direct to mail doesn?t work. But it should to work.!!! I think that was the error. Later after creating separate group and adding mail to it, it?s working fine.. Any idea here? why doesn?t work if I changed dovecot-lda direct to mail group instead of creating new group and adding mail to it???.
