Hi Randy, I would give the package 'mail-filter/policyd-weight' a try to stop this unwanted mails.
But keep in mind to have some 'check_sender_access' and 'check_recipient_access' files on hand to bypass the fail-positives senders and recipients. Example: # postconf | grep 'smtpd_recipient_restrictions' smtpd_recipient_restrictions = permit_mynetworks, check_sender_access hash:/etc/postfix/sender_checks, check_recipient_access hash:/etc/postfix/recipient_checks, check_policy_service inet:127.0.0.1:12525, warn_if_reject reject_unknown_sender_domain, warn_if_reject reject_non_fqdn_sender, warn_if_reject reject_unknown_recipient_domain, warn_if_reject reject_non_fqdn_recipient, warn_if_reject reject_unauth_pipelining, warn_if_reject reject_unauth_destination, permit_auth_destination, reject Regards, Olaf Niermann -----Original Message----- From: Randy Barlow [mailto:[EMAIL PROTECTED] Sent: Friday, November 30, 2007 8:00 AM To: [email protected] Subject: [gentoo-server] SMTP Woes I am getting a huge number of connections to my mail server (postfix) compared to usual. I've seen as many as 50 connections open at one time. The logs show that the connections are from several computers of varying IPs, and they are all trying to send mail to random mailboxes on my domain. It's very annoying, and I have noticed that inbound mail seems to be lagging by several hours. Is there something similar to denyhosts for spammers? Any other suggestions? -- Randy Barlow http://electronsweatshop.com -- [EMAIL PROTECTED] mailing list -- [EMAIL PROTECTED] mailing list
