MAIL FROM: <""> ??

[Marek Kozlowski]

:-)

When testing my server via telnet ... 25 it works:

MAIL FROM: <"">
250 2.1.0 Ok



BTW:

MAIL FROM: <>
503 5.5.1 Error: nested MAIL command
MAIL FROM: ""
503 5.5.1 Error: nested MAIL command

Best regards,
Marek

Moreover an active 'reject_sender_login_mismatch' restriction not blocked mail from SASL authenticated user (a compromised account) with such an envelope address. What have I missed?
