It looks like the only rejection messages that are being sent is the one when a connection is refused based on a RDNS querry. I haven't changed anything on the customize settings so I'm not sure what is going on. any ideas? |

Please note that rejection "errors" are sent to the remote server during the SMTP commands transactions. An error email message is not generated and sent to the sender. This said, what verison of SpamFilter are you using? As far as we know, all error codes are functioning. Can you provide a specific example of what is happening? Roberto Franceschetti |

It may just be my own ignorance, so I appologize in advance if it is. I am running v1.1.2.122.. This is an error someone got because they did not have a reverse lookup for the mail server...... -----Original Message----- Your message did not reach some or all of the intended recipients. Subject: LJL The following recipient(s) could not be reached: example@lamarhq.com on 6/3/2003 10:56 AM This is the rule on the customized items page "557 Your IP %IP% does not have a reverse DNS entry. Disconnecting..." If I am understanding you, this error message should have been sent/communicated with the users email server when attempting to transfer the email.... So will the user ever see this?? Thanks again. |

Hi Peter, With your example we now understand what you meant. You have a very valid question. This the SMTP conversation that takes place when a remote server does not have a valid reverse DNS entry: >>220 mail2.netwide.net Welcome to LogSat's Software ESMTP Server v1.2.0.143 - Beta Test Version >>250-AUTH LOGIN <<RSET >>250 Ok <<MAIL FROM:joe@domain.com >>250 joe@domain.com Address Okay <<RCPT TO:roberto5@logsat.com >>250 roberto5@logsat.com Address Okay <<DATA >>354 Start mail input; end with <CRLF>.<CRLF> <<From: joe@domain.com <<To: roberto5@logsat.com <<Subject: Re: test 1 <<Date: Tue, 2 Jun 2003 21:08:37 -0400 <<Content-Type: text/plain;charset="ISO-8859-1"; << <<test body txt <<. >>550 Your IP 172.27.4.51 does not have a reverse DNS entry. Disconnecting... At this point the remote server receives the 550 error message. It is up to the remote SMTP server at this point to send an email back to his user (the sender) to let them know of the problem. Usually remote servers behave well and will include in their error email to their users (the sender) the reason of why the email was not delivered (550 Your IP 172.27.4.51 does not have a reverse DNS entry. Disconnecting...). In your example this did not happen, the remote server decided to output its own (incorrect) message. This is not the norm, usually remote mail servers do display the correct error. We have seen that if you disable the quarantine (causing the reject error to be displayed to the remote server immediately, before it has a chance to send the email body), these misbehaving servers are more likely to include the correct error.
