They might have been shortened by RFC 5321 (only 10 years ago), but weren't -- satellite can be terrible and links into disaster areas can be worse, not even counting personal or overloaded servers (as was suggested, taking a while to scan content). General aviation crusing at 100kts continues even while others fly or ride 5 times faster -- I see similar in SMTP/networking/servers; hell a hundred-fold difference probably exists between my home and your employer's datacenter yet either of us can source or sink SMTP sessions -- I'd not need 10 minutes to scan but it is nice that I am (they are) not required to run races just because others can/do/must. That being aside from what we actually practice despite the rules (guidelines it sometimes seems). /mark _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
