This directory contains the source files for mail.local. This is not intended to be used on *stock* System V derived systems such as Solaris or HP-UX, since they use a totally different approach to mailboxes (essentially, they have a set-group-ID program rather than set-user-ID, and they rely on the ability to "give away" files to do their work). If you choose to run *this* mail.local on these systems then you may also need to replace the existing MUAs, as well as IMAP and POP servers, with ones that are compatible with the BSD interface. You have been warned! For systems with maillock() support, compile with -DMAILLOCK and link with -lmail to use the maillock() routines. This can be accomplished in your site.config.m4 file with: APPENDDEF(`conf_mail_local_ENVDEF', `-DMAILLOCK') APPENDDEF(`conf_mail_local_LIBS', `-lmail') Defining CONTENTLENGTH (-DCONTENTLENGTH) will build a mail.local which outputs a Content-Length: header. Solaris 2.3 and later will automatically include Content-Length: support. This can be accomplished in your site.config.m4 file with: APPENDDEF(`conf_mail_local_ENVDEF', `-DCONTENTLENGTH') Defining MAILGID to a 'gid' (-DMAILGID=6) will cause mailboxes to be written group writable and with group 'gid'. This can be accomplished in your site.config.m4 file with: APPENDDEF(`conf_mail_local_ENVDEF', `-DMAILGID=6') mail.local will not be installed set-user-ID root. To use it as local delivery agent without LMTP mode, use: MODIFY_MAILER_FLAGS(`LOCAL', `+S') in the .mc file. Defining HASHSPOOL (-DHASHSPOOL) will build a mail.local which supports delivering to subdirectories of the mail spool, based on a hash of the username (i.e., a hash depth of 2 and a username of "user" will result in /var/spool/mail/u/s/user). If the hash depth is greater than the length of the username, "_" will be used. The necessary subdirectories must exist; mail.local will not create them. Use the "-H" option to set the hash type and depth (like "-H u2" for a username hash two levels deep). The HASHSPOOL option also adds two other options: "-p path" to specify an alternate mail spool path (i.e., "-p /local/mail") and "-n" to specify that mail.local should not strip the @domain part of recipient addresses in LMTP mode. In addition to HASHSPOOL, defining HASHSPOOLMD5 and linking against libcrypto from OpenSSL like: APPENDDEF(`conf_mail_local_ENVDEF', `-DHASHSPOOL -DHASHSPOOLMD5') APPENDDEF(`conf_mail_local_LIBS', `-lcrypto') will offer an alternate hash, using a base64 encoding (changing / to _) of an MD5 hash of the username. This results in a more balanced subdirectory tree. The subdirectories will be named with A-Z, a-z, 0-9, +, and _. The hash type is "m", so use "-H m3" to get a three level MD5 based hash. $Revision: 8.11 $, Last updated $Date: 2003/10/20 20:19:13 $
