/* 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!

 * there is a problem inside the SMTP transaction. However, we can't find that out without
 * actually initiating something, and that would be bad. The logic here helps us
 * correctly recover from an unreachable/down mail server, which is probably the majority
 * of problem cases. For SMTP transaction problems, we will do lots of retries, but if it
 * is a temporary problem, it will be fixed anyhow. So I consider this implementation to
 * be clean enough, especially as I think other approaches have other weaknesses.
