If it's mails from the broken Lotus Notes client that's the problem (and they're the only ones we saw here), it's caused by a null Message-ID header; just have your SMTP server remove those. LMTP will generate a new, valid message-id when the message is delivered.Hello, from time to time we are getting this message in our exim logs: LMTP error after end of data: 554 5.6.0 Message contains invalid headerI have also experienced this error while I'm syncing emails from an old server to our new cyrus mailserver. I havemunge8bit: falsein my imapd.conf and reject8bit is set to "false" by default. Which headers is cyrus complaining about? I cannot change this world where clients like Notus Notes are sending invalid emails, but simply refusing these mails is a bad choice. And we also have a lot of emails we received in the old setup and I wouldn't know how to explain to our users, that they cannot access these messages any more.How can I make cyrus less strict?
in Exim:
headers_remove = ${if match{$h_Message-ID:}{\N^\s*$\N} {Message-ID} {} }
cheers,
Adam.
