Invalid SMTP protocol:

[huki]

Hi together.
I have this log message:

Feb 11 10:14:48.546 fw smtp[388]: 218 smtpd: Invalid SMTP protocol: Overly long line received from mail.net-nachtexpress.de ([194.25.224.8])

After this log entry the mail will be blocked!
What's my problem an how i can fix it?
Thanks Huki

Look at the log closely, does it state that the body of the email was greater than 1024? This firewall seems to have a body length blocker.

This is controlled in the config.cf. The entry is smtpd.max_body_line_length=1024. You can change this, but its highly inadvisable. SECURITY ISSUE.It would be better to contact the sender and have them change the line length in their e-mail.
