does IBM count?
their canadian arm was a problem for a while and i had to whitelist
their outgoing MTA. this has since been fixed, but stuff like this
pops up from time to time, usually for 'small' companies but
occasionally for large. currently, the only thing in my
graylisting whitelist file is (shudder) facebook. (don't get me
started about them...)
it's not (IMHO) enough of an issue to avoid using graylisting. just
be aware that it IS an issue from time to time, and the occasional
Big Player might well be involved.
