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

Edit the config.cf file in the raptor management console ( right click on Firewall then "All tasks_Editor&quotUncheck (remove #) where "smtpd.max_body_line_length=4096" and increase line length size, e.g. this size of 4096.
Hope this answers your query
