The purpose of these is to check that our SMTPd inter-operates successfully with everyone else's SMTP client software. Feel free to add a test script for your favourite other language - or to improve the usage of any of the current languages. mail-test.pl - Perl test script mail-test.py - Python test mail-test.rb - Ruby test mail-test.php - PHP test (requires some php.ini configuration) php.ini - PHP ini file (default for Windows installations) mail-test.tcl - and of course, a Tcl client!
