Hi, Since I never got a response from my previous post, I assume my question was lame or lacked detail. I'll try again... Is there anyway I can configure vchkpw to handle APOP for /etc/passwd users? I know there are other means for handling this (patches to checkpassword, checkpw, etc.) but I like the logging features of vchkpw and the fact if configured, will maintain the relay cdb. I do NOT (at least at this time) wish to use vpopmail other than to maintain the relay cdb and for authentication. From investigation it appears virtual apop users' passwords are stored in clear text in order to match md5 hashed copies sent across the wire. Qualcomm's qpopper supports the use of APOP with /etc/shadow-- can vchkpw offer the same? Just curious, anyone know how qpopper utilizes /etc/shadow with APOP? I ask only because from searching the qmail archives it appears passwords need be stored in clear text on the server. The qmail site offers numerous alternatives, but if vchkpw can use /etc/shadow with APOP authentications, then I won't have to change the auth mechanism. A response of any sort would be appreciated. many thanks, --James
