What are people doing in relation to this?
Until now, I have been using postfix to send mail for
client@clientsdomainto their real email address, but this fails for
the reasons given when
people unfortunate enough to use yahoo. com (or, more rarely, AOL) email
them.
I could switch to running a mail server for them, rather than forwarding,
but it involves them changing things. And it will be a pain for me.
I could collaborate with breaking RFCs and change the from: line of the
header (is there an easy way to do that which ensures that there is a
reply-to: line which adds the old from: if necessary?) but I don't really
want to do that.
Or I could say 'tough, no more using client@clientsdomain', but they don't
want that.
