1.1 - How to understaned a word TPmail?

TPmail is possible to understand as TransParent Mail.

1.2 - Will be TPmail available for other platforms than FreeBSD?

TPmail was ported on Linux and Solaris for x86 systems. But before a ready package shipping for these platforms it is neccessary to run an serious external testing. Only after finishing of these testings the package will be ready for a commercial shipping. We are looking for any organization that ready to run a such external testing with a very good partnership conditions.

1.3 - Will be TPmail supported other mail servers sendmail?

TPmail is initially created as a package only for mail server sendmail. But interests for many features of package is forced us to try to port some features, for example, anti-spam filter. Such work had stared and we selected a mail server Communigate Pro as first target. Here alsoe we are looking for organizatioins to help us with the external testing.

1.4 - How to get a demo version of TPmail for evaluation purpose?

Write a request. We will be discuss it.

1.5 - Upgraded TPmail, but again started old version. What to do?

Please read a documentation. After stop of sendmail and modules of package TPmail you must sure that, a given programs really stopped. For this checking use the standard system programs ps and sockstat.

1.6 - Statistics in TPmail is very good, but I wanted a more like ...?

Statistics program in the package TPmail consists of two parts. First part ÞÁÓÔØ transforms logs of sendmail into some internal form (chains of messages and events). Second part - this is a report generator. We agree with some our partners, that various reports generators will be more successfull to create the various reports forms during a statistics ouput. Maybe in next version we will be ready to build to implement a such possibility. Note that this possibility is partially implemented now. Please note also that all such features will be need a wide testing to provide an effective implementation.

1.7 - There exist so called multiprocessing technologies. Do you have a something like in TPmail?

Multiprocessing technologies are allowed on SMP systems simultaneously to run a several tasks for one message, for example, virus checking with several antiviruses scanners simultaneously. Package TPmail is eay allowed to implement multiprocessing technology with any scaling unlike other packages. Sample of such implementation you can see in script run_all_virus_scanners.sh for module milter-agent.

1.8 - Please give a simple explanation of mail routing in TPmail to write own filtering rules?

All mail that gets a mail server sendmail is incoming mail (use the standard post office as example). On next stage, using of e-mail envelopes and own settings, sendmail selects a match route for a given message. Namely, for sendmail settings we speak oftly about incoming and outgoing mail. In really, sendmail is only retranslated (reroutes) a message on next selected server or local delivery agent. Any milter module don't know something about a messages's route. Milter modules of package TPmail are same as other milter modules. They use a global filters and don't understand a traffic direction. Therefore, a created rules are acted for all messages. But in some cases, when we provide TPmail a some additional information, then its modules will be understand a traffic direction (incoming and outgoing messages). Such example will be the automatic white lists by sender in module milter-connect. And therefore, during own filtering rules please note that TPmail don't know anything about mail messages routing.

Added a rule into static white list. It doesn't work. What to do?

Check, that you are not missed a keyword [Filter] in rule definition. Next with a log of module milter-connect or with a helo of program mc_client you must sure, that a given was successfully loaded. If in this rule you use the regular expressions, then check it with a help of program test_regex. And last - check your rule for matching on real parameters wanted mail messages, that must be filtered by your rule. Please read carefully a logs. Increase a verbosity level for a more detail diagnostics.
