If you do "dig home.isbd.net MX" or "dig isbd.net MX" as command lines,
is the answer the IP for the machine you expect to handle your mail?

Don't have "dig"?  Install it...

Mail uses MX records, when done properly, not A records (nor entries in
hosts file, I think - I think MX will supersede them, too).

If the MX record points to somewhere else, that's where the mail will go
to.  Is this domain your own, or are you making use of your ISPs?  And
is it set up properly.

(I've done a whois lookup, but that's no guarantee that we're chatting
to the same person.)

Don't send private replies to my address, the mailbox is ignored.
I read messages from the public lists.
