NethServer Version: 7.3.1611
Hello Nethserver Team
since February we are using nethserver as our production server and are quite happy with it.
I just discovered that I have a lot of error or warning messages in my root-mail account of the following type:
Warning: filter Filterexternal spamc (allow_root_commands="False", arguments="('-E', '-s', '250000')", command="spamc", exitcodes_drop="('99', '100')", exitcodes_keep="('0', '1')", group="amavis", ignore_stderr="False", path="/usr/bin/spamc", unixfrom="False", user="amavis") returned fewer headers (46) than supplied (47)_
I am using the POP3_connector to get emails from our provider into Nethserver. I have also the spam-check activated. Obviously there is a problem calling the external program spamc that checks messages for spam.
Is this just a warning message that can be ignored?
What irritates me, is that yesterday I think that we did not receive at least one email message. The sender informed me by telephone that he sent the email yesterday and I could verify that in the mail message log-file. there it looks like the message would have been delivered but we can't find it in the inbox folder where it was supposed to be delivered (i also checked the spam folder).
Is it possible that if the spam check fails the message is not going to be delivered? Is there a way to recover it?
Thanks a lot in advance for your answer. If you need more information, please tell me.
