mail from: <>
250 <> is syntactically correct

2.6.1. "MAIL From: <>"
The MTA MUST NOT refuse to receive "MAIL From: <>".
The "MAIL From: <>" address is used in error messages from the mail
system itself, e.g. when a legitimate mail relay is used and forwards
an error message back to the user. Refusing to receive such mail
means that users may not be notified of errors in their outgong mail,
e.g. "User unknown", which will no doubt wreak more havoc to the
mail community than spam does.
The most common case of such legitimate "MAIL From: <>" is to one
recipient, i.e. an error message returned to one single individual.
Since spammers have used "MAIL From: <>" to send to many recipients,
it is tempting to either reject such mail completely or to reject all
but the first recipient. However, there are legitimate causes for an
error mail to go to multiple recipients, e.g. a list with several
list owners, all located at the same remote site, and thus the MTA
MUST NOT refuse "MAIL From: <>" even in this case.
However, the MTA MAY throttle down the TCP connection ("read()"
frequency) if there are more than one "RCPT To:" and that way slow
down spammers using "MAIL From: <>".
