MUAs receive email via POP or IMAP, protocols in which Postfix plays no
role. So those issues are out of scope here. To report a problem
sending email via Postfix, see:
http://www.postfix.org/DEBUG_README.html#mail
If the client reports a plausibly useful error message (or records
something relevant in some activity log), send that along as well.
