openQmail

There are several interesting external resources that could be useful.

Some of the documentation here is valid for openQmail in general or most cases, some of it is may be useful to find a partial solution.

• Life with qmail - the quasi standard of a qmail installation
• The djb way - a quite good documentation along djb's way and software
• qmail.org - mostly outdated, some tips are may be still useful
• DynDN.eS Blog - some related articles and tutorials         Important!
• qmail howto by “jsd” -

• qmail Anti spam howto by Chris Hardie

The community provides good stuff too.

• Sam Varshavchik's courier-authlib - the preferred way of eQmail
• couriercheckpassword by Andrew Richards to authenticate against the courier-authlib
• Bruce Guenter provides several additions, e.g. mailfront

There are some “big” patches and sites with multiple patches. The “big” patches are not used by openQmail, but some ideas are “stolen”.

• Roberto Puzzanghera's (all-what-exists) patch and blog (active)
• John M. Simpsons combined patch and other documentation (discontinued)
• Qmail Patch Explanations and Recommendations by Kyle Wheeler
• qmail-spp - the patch is a fix part of openQmail

The forks with active maintenance have dependencies which are not acceptable by openQmail's philosophy.

• indimail, an active maintained fork by Manvendra Bhangui
• s/qmail, active maintained by Erwin Hofmann, a bit to academic and over-featured, away from practice
• dirqmail - the smtpplugins patch (qmail-spp) was derivative from here, otherwise the project seems to be dead
