Indeed. Both sendmail and postfix (and presumably also at least some other MTAs) allow you to set queueing periods on a per-domain or per-recipient basis (or some mix thereof), and you can set the queue retry to be a very extended period of time -- even infinite, if you desire. Running this on a backup MX server would definitely serve the same purpose as UUCP. It does require some configuration support on the part of the operator of the backup MX, but that's about it. BTW, last time I checked, EC2 was prohibited from being used for any e-mail related activity. Those ports are permanently blocked, both incoming and outgoing. This prevents spammers from using EC2 to hide their activity. But a fairly standard VM hosting account at one of the major providers should be configurable to do what is required. -- Brad Knowles <[email protected]> LinkedIn Profile: <http://tinyurl.com/y8kpxu> _______________________________________________ Discuss mailing list [email protected] http://lists.lopsa.org/cgi-bin/mailman/listinfo/discuss This list provided by the League of Professional System Administrators http://lopsa.org/
