Two firends have told me that some ISP refuse sending thought their relay
not only messages "in transit" but even messages originating from their
dialup lines, unless they use a From address of one of their users.
So if one has another address and want to send a message with that one
has to resort to direct mailing from their dialup machine. How can you
cope with it ?
