/* ommail.c
 *
 * This is an implementation of a mail sending output module. So far, we
 * only support direct SMTP, that is talking to a SMTP server. In the long
 * term, support for using sendmail should also be implemented. Please note
 * that the SMTP protocol implementation is a very bare one. We support 
 * RFC821/822 messages, without any authentication and any other nice
 * features (no MIME, no nothing). It is assumed that proper firewalling
 * and/or STMP server configuration is used together with this module.
 *
 * NOTE: read comments in module-template.h to understand how this file
 *       works!
