sf ver: v2.7.1.532 listening on 25 - ip: xx.xx.32.31 customer sends mail from outlook client using smtp auth with their domain. They cannot send email to local or external domains. It seems to be blocking the mail because the IP their ISP is giving them is blacklisted. Why is this happening? How can I prevent it? 08/20/06 14:12:16:406 -- (1136) Connection from: xx.xx.116.202 - Originating country : United States ------------- http://www.propercc.com |

note: sendersdomain.com & recipientdomain.com are both LOCAL domains on the server and are both in the "local domains" list. if mailto:sender@sendersdomain.com - sender@sendersdomain.com sends email to a gmail account the same happens as well... this was to clarify my rambling... -c ------------- http://www.propercc.com |

SpamFilter by default denies any attempt to relay emails to domains that are not in its list of "Local Domains". Prior to v3.1, the only way to allow users to use SpamFilter as their "outgoing smtp server" is to add the IP(s) of the users in an IP whitelist. This will allow users to send emails to any domain, and to avoid being blocked. In your example, SORBS correctly blocked the user as SORBS blocks any dynamic IP. Please note that even if the client has smtp auth enabled, it's not supported in your version of SpamFilter. Starting with SpamFilter 3.1, we added support for SMTP auth (including SSL encryption). Active Directory, LDAP, and Unix-style passwords can be used to authenticate senders. If a sender is authenticated successfully, they will be whitelisted and allowed to relay. ------------- Roberto Franceschetti http://www.logsat.com" rel="nofollow - LogSat Software http://www.logsat.com/sfi-spam-filter.asp" rel="nofollow - Spam Filter ISP |

What if I were to do the following: Give SF a ip different from my mailserver, just say xx.xx.47.53 and have it listen on 25. Set my mail server (xx.xx.32.31) back to listen on 25. change the following dns entries: create an A record for spam.domain.com and point it to xx.xx.47.53 wouldent this work? Dont get me wrong if this software works good for me I'll buy your new version. -C ------------- http://www.propercc.com |

Yes, the configuration you described will work just fine! As a side note, while we do not have the latest version available as a "free" test download, if you wish to try it please contact us at sales at logsat dot com, we'll be able to help. ------------- Roberto Franceschetti http://www.logsat.com" rel="nofollow - LogSat Software http://www.logsat.com/sfi-spam-filter.asp" rel="nofollow - Spam Filter ISP |
