Hi, Running postfix as an MTA I have the problem that postfix accepts mail with non-ASCII chars in MAIL FROM envelope and cyrus-imapd's lmtpd rejects them with "501 5.5.4 Syntax error in parameters". >From what I understand 8bit envelopes are allowed according to newer RFC's and I'm wondering if it's correct that cyrus-imapd blocks them if they are found in MAIL FROM, not RCPT TO?
I know it's possible to use check_sender_access in postfix to stop those mails from being accepted, but it seems it could still block legitimate mails despite that fact that those from adresses may be 99.9% spam. How do others deal with this issue?
