Policy server problem: connection timed out or connection reset by peer
Dear all, I got a problem with my own Postfix policy server (written in Python). Postfix usually works fine with it, but sometimes it raised error like this: Aug 17 08:32:52 mail1 postfix/smtpd[24298]: warning: problem talking to server 127.0.0.1:1234: Connection reset by peer Aug 17 08:34:05 mail1 postfix/smtpd[24771]: warning: problem talking to server 127.0.0.1:1234: Connection timed out Then time Postfix raised these errors, my policy server is still working and properly processing requests (checked its log file). I don't know how to reproduce this issue, except wait (especially when server is busy, but randomly). Do you have any idea/hint about how i can debug this issue? either Postfix side or my policy server side, or both. Your help is greatly appreciated.

Postfix is configured to call the policy server at protocol state RCPT (smtpd_recipient_restrictions) and END-OF-MESSAGE (smtpd_end_of_data_restrictions). I understand what a policy service does, just want to know whether or not Postfix parses the submitted mail message to get 'From:' address and send it to policy server. This is not mentioned in Postfix doc: http://www.postfix.org/SMTPD_POLICY_README.html > The From: is a header instead of a smtp protocol field. > It may be only available within a header check. This makes sense. But with header check, you get one header each time, we cannot compare two headers. A content filter should work in this case, but it's not my purpose.

No From: address in policy delegation protocol?
Dear all, I have a simple Postfix policy server, and got a problem to reject sender login mismatch (sender != sasl_username) with Outlook 2016: user is able to specify a From: address, it would be any address you want, and the From: address is not passed to policy server. I can reproduce this issue with a simple Python program: *) construct mail message with forge sender address. e.g. 'From: ' *) send email as normal/legal user "auth_u...@my-domain.com" with smtp auth. *) while sending email, specify the sender address as "auth_u...@my-domain.com". *) When user received the email, his MUA shows the address in 'From:' as sender. In this case: - address 'fo...@forge.com' is not available in policy server - attributes 'sender=' and 'sasl_username' are 'auth_u...@my-domain.com' So the question is, does Postfix parse the submitted mail message to get 'From:' address? How can i overcome this? Thanks for helping. :)

Feature request: able to search sql/ldap without extension (user+extens...@domain.com)
Dear Postfix developers, I posted a question about how to construct a sql/ldap query to query accounts without extension part in email address last month: http://marc.info/?t=14260881834&r=1&w=2 For example, query recipient 'user+extens...@domain.com' with LDAP filter: query_filter= (mail=%s) query_filter= (mail=%u@%d) It will always include '+extension' part in filter. The feature i'm requesting is to add one more expansion (e.g. %n) which doesn't include '+extension' part. For example: query_filter = (mail=%n@%d) It will query 'u...@domain.com' without '+extension' part. I know we can use some SQL builtin functions to construct this query filter, but it's impossible for LDAP. That's why i'm requesting this feature. Hope you can consider my request and implement it in future release. Thanks. :) iRedMail project: http://www.iredmail.org/

That will filter out keys with no @domain part. Thanks Victor. :) I'm afraid that '%u' doesn't work, it still has '+extension' in query. for example: *) part of my testing ldap lookup file: query_filter= (mail=%u@%d) *) Testing with 'postmap': # postmap -v -q 'postmaster+...@mydomain.ltd' ldap:./my_ldap_file.cf ... postmap: dict_ldap_lookup: ./my_ldap_file.cf: Searching with filter (mail=postmaster+...@mydomain.ltd) ... As you can see, '%u' doesn't drop extension '+abc' in my test. Anything wrong in my testing?
About table search order: not to query 'user+extens...@domain.ltd'
Dear all, According to Postfix document, virtual(8), 'user+extens...@domain.ltd' is looked up first, then 'u...@domain.ltd'. Is it possible to skip/ignore the address extension and just query 'u...@domain.ltd'? (by the way, i want to ignore the extension in SQL/LDAP lookup.) Thanks for your time and help. :) TABLE SEARCH ORDER ... The search order is as follows. The search stops upon the first suc- cessful lookup. o When the recipient has an optional address extension the user+extens...@domain.tld address is looked up first. o The u...@domain.tld address, without address extension, is looked up next.

Dear all, I wrote a simple daemon service in Python, it's used in Postfix transport_maps like this: transport_maps = tcp:127.0.0.1:1234 It always returns '200 my_transport\n' as described in Postfix manual page tcp_table(5), but Postfix always complains "unexpected EOF" like below: Jul 27 22:51:53 d7 postfix/trivial-rewrite[4260]: warning: read TCP map reply from 127.0.0.1:1234: unexpected EOF (Success) This Python daemon server uses 'asynchat' module, and return '200 my_transport\n' with 'async_chat.push()' method like this: self.push('200 my_transport\n') Any idea why Postfix always complain "unexpected EOF"?

If we have 1 users, which maildir path style will improve performance? The performance will depend on the underlying file system. Different file systems handle large directories in different ways. To find out, you would need to do measurements. Postfix has smtp-source (and smtp-sink) tools for stress testing. Wietse Thanks Wietse & Sahil. :) -- Best regards.

That's an odd porting philosophy. The conventional practice is to feed your diffs back to the original developers so ideally it will become multi-platform. Hi, Rod. Thanks for your reply. I'm the original developer, I spent most time to make this solution full-featured on *ONE* distro (RHEL/CentOS). When it seems to be stable, i will try to make it work on other distros, such as Debian, SuSE, OpenBSD. -- Best regards. - Open Source Mail Server Solution for RHEL/CentOS 5.x: http://code.google.com/p/iredmail/
