This can be useful for users behind restrictive firewalls that only allow Mail-Access (usually through a central mailhub). In a situation like the above, it's possible to use mailtunnel to tunnel anything from simple telnet sessions to SSH-PPP VPNs (practically anything that can be tunneled over TCP/IP) to a non-blocked system on the internet. This allows users(well..) behind even the nastiest firewalls to access resources they're not ment to access." http://www.detached.net/mailtunnel/ "Potential Problems: * There's no sequence number resulting in Duplicate or dropped packets. * There's no From:-source-address-check, spoofing is easy. (Fix: Let procmail do the from-filtering) * Extreme latency. Today's mailingsystems are terribly slow, resulting in ping replies up to an hour, maybe more." /magnus -- http://x42.com/ ===8<===========End of original message text=========== Best regards, Martin mailto:[EMAIL PROTECTED] -- Sent to you via the frendz list at marsbard.com The archive is at http://www.mail-archive.com/[email protected]/
