Not that I can see.

Yes. So your problem is not with authentication.

What makes you think that that is the reason?

That seems more likely. It also seems like a very good reason to
reject the message.

You could bypass whatever part of the RCPT ACL is causing the
rejection (most likely a verify = sender) for authenticated sessions,
but IMHO that would be a Bad Idea.

Put another way, provide a valid address as sender. That's the right
answer.

| How can I do if any of the two aspects workable? Can I rewrite MAIL FROM address?


Why can't you just configure the MUA or script you are using to send
the message to specify a valid sender address? I don't see any
reason to try to work around your broken client in exim.

What we needed to see is the ACL that's causing the rejection
(acl_check_rcpt).
