*FIXED* Hi All, I have just completed putting together a spam snake using the software and how-to named The Perfect SpamSnake - Ubuntu Jeos 12.04 LTS Precise Pangolin, which is put together very nicely. However I can't seem to receive email from the outside world. If I telnet into the server from a machine inside the local network I am able to send an email to a user hosted on my exchange 2007 email server, but when I try from external sources I get an error. I also can't receive email from my googlemail account. I have attached a copy of the mail.log, however if you need more information I'll gladly post it. Thanks in advance, Rod. #####Telnet from outside local network##### 220-ESMTP SpamSnake ehlo britishint.com 250-spamsnake.______.co.uk 250-SIZE 10485760 250-ETRN 250-STARTTLS 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN mail from :[email protected] 250 2.1.0 Ok rcpt to: [email protected] 550 5.5.1 Protocol error #####Telnet from within local net##### 220 ESMTP SpamSnake ehlo britishint.com 250-spamsnake.______.co.uk 250-PIPELINING 250-SIZE 10485760 250-ETRN 250-STARTTLS 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN mail from: [email protected] 250 2.1.0 Ok rcpt to: [email protected] 250 2.1.5 Ok data 354 End data with <CR><LF>.<CR><LF> subject: Test Message Hello . 250 2.0.0 Ok: queued as 3E9FE5A98
OK ... a little sleep helps: I have found the issue to be with the line below in main.cf: smtpd_recipient_restrictions = reject_unauth_destination, permit_mynetworks, permit_sasl_authenticated, reject_unknown_recipient_domain, whitelist_policy, grey_policy, spf_policy, rbl_policy, permit spf_policy causes the following error: Feb 8 13:25:45 spamsnake postfix/smtpd[1051]: warning: connect to private/policy: No such file or directory Feb 8 13:25:46 spamsnake postfix/smtpd[1051]: warning: connect to private/policy: No such file or directory Feb 8 13:25:46 spamsnake postfix/smtpd[1051]: warning: problem talking to server private/policy: No such file or directory Feb 8 13:25:46 spamsnake postfix/smtpd[1051]: NOQUEUE: reject: RCPT from mail-ee0-f53.google.com[74.125.83.53]: 451 4.3.5 Server configuration problem; from=<[email protected]> to=<rod@______.co.uk> proto=ESMTP helo=<mail-ee0-f53.google.com> rbl_policy causes the following error: Feb 8 13:24:18 spamsnake postfix/smtpd[952]: connect from mail-ea0-f181.google.com[209.85.215.181] Feb 8 13:24:18 spamsnake postfix/smtpd[952]: warning: unknown smtpd restriction: "rbl_policy" Feb 8 13:24:18 spamsnake postfix/smtpd[952]: NOQUEUE: reject: RCPT from mail-ea0-f181.google.com[209.85.215.181]: 451 4.3.5 Server configuration error; from=<[email protected]> to=<rod@______.co.uk> proto=ESMTP helo=<mail-ea0-f181.google.com> If anyone can shed some light as to how to resolve these two issues I would be very grateful.

Right ... fixed the SPF problem using info on this link: https://help.ubuntu.com/community/Postfix/SPF Basically remove spf_policy and replace with Code: check_policy_service unix:private/policy-spf Leave all other settings as is regarding SPF I am assuming in my noobiness that this is doing the intended job.
... and rbl issue is fixed... postfix did not like referencing made up rbl_policy instead added the following directly to smtpd_recipient_restrictions: reject_rbl_client zen.spamhaus.org, reject_rbl_client bl.spamcop.net, so now line reads: Code: smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unknown_recipient_domain, reject_unauth_destination, whitelist_policy, grey_policy, reject_rbl_client zen.spamhaus.org, reject_rbl_client bl.spamcop.net, check_policy_service unix:private/policy-spf, permit Thanks for letting me air my problems ;-)
