Re: Any C api to access Postfix programmatically?
2009/8/24 Δημήτριος Καραπιπέρης dim...@thessaloniki.gr: I came to this solution, a bash script to validate a local recipient employing the SMTP protocol. Depending on your config, wouldnt you also be able to use 'postmap -q' or 'postalias -q' to directly query a particular lookup table? That would avoid a network connection and avoid cluttering logs with your half completed connections. I suppose talking SMTP lets you take advantage of some of the smarts that postfix uses to do more recursive type lookups or any other validations that might happen in the background. (recursive as in, in an access table, attempt to match u...@host.example.com, then try host.example.com and .example.com etc. Apologies if I have misunderstood how the access tables do their matching - Im a noob) -- Phill
Re: Any C api to access Postfix programmatically?
Users source could be ldap or mysql, not a hash file. In essence, I need to employ the local_recipient_map property, which holds all the valid recipients of the particular Postfix instance.

In essence, I need to employ the local_recipient_map property, which holds all the valid recipients of the particular Postfix instance. You can use postmap -q to make such queries, ldap or mysql works just the same as querying a hash file. That aside, this has the potential to be complex anyway, so using SMTP after all isn't unreasonable.

I came to this solution, a bash script to validate a local recipient employing the SMTP protocol. #!/bin/bash nc localhost 25 EOF | grep '250 2.1.5 Ok' | sed 's/250 2.1.5 Ok/OK/' HELO localhost MAIL FROM: dim...@thessaloniki.gr RCPT TO: $1 QUIT EOF Dimitrios O/H Wietse Venema έγραψε: ? ???: Hi ! Is there any Programming Interface (api) , so that a Postfix instance could be accessed programmaticaly, say, a C program? Currently, all the SUPPORTED interfaces require that non-Postfix code communicates with Postfix via some protocol: examples are the SMTP protocol, the pipe-to-command protocol, the SMTPD policy protocol, the Milter protocol, and a simple TCP-based lookup table. for example, connect to a Postfix instance and validate if an e-mail address is a valid recipient for the specific instance... You can already do this with the existing SMTP interface. Wietse
Any C api to access Postfix programmatically?
Hi ! Is there any Programming Interface (api) , so that a Postfix instance could be accessed programmaticaly, say, a C program? for example, connect to a Postfix instance and validate if an e-mail address is a valid recipient for the specific instance... thanks Dimitrios Karapiperis

Maybe just speak SMTP to it? I'm sure there are SMTP libraries already written and available. for example, connect to a Postfix instance and validate if an e-mail address is a valid recipient for the specific instance... I think for this, you would do better to simply consult whatever backend the Postfix instance is using for recipient validation. -- Offlist mail to this address is discarded unless /dev/rob0 or not-spam is in Subject: header
