NetBSD, as almost all Unixes, brings a mailserver (Postfix) along with its standard system.
This mailserver is enabled by default to let outgoing mails through, but most mailservers won't accept mails from dial-up networks. So the most common way is to use another mailserver with your common mail account to relay mails.
Your task is to write a small wrapper that does the authentication needed for most SMTP relays, such that a user only has to insert his account details for e.g. Gmail and then can relay the system mails there.
You should also take into account relaying the system user's mails to that account or document how you would do so. This would entail (though this is not part of this task) having a configuration for several users, such that they can setup this for themselves without others seeing their password.
This task doesn't have to be necessarily code, a comprehensive guide on how to do this by hand would also be sufficient (but not obsoleting the coding task).

What language would you want this to be in?
I don't have much experience with NetBSD, so I don't know what comes with the system (e.g. Python, Ruby).
I mean programming language :P
NetBSD has only standard Unix languages (C/C++, AWK, sh) and Lua.
You may use Python or make another reasonable choice, if you want.
(You do not need to reimplement ESMTP and cryptographic software for this task.
In fact you're strongly advised not to do that, use some stock software.)
I would like to work on this task.
This task has been assigned to Matthew. You have 240 hours to complete this task, good luck!
The work on this task is ready to be reviewed.
Matthew asked me about this in #netbsd-code, and I looked at it. The task itself is written confusingly, so I'm not sure what's missing.
His script (which claims python 3.2, but worked OK on 2.6) works well to forward a system user's email to an external address (which is one of the things described, I believe).
As far as relaying goes, that's not covered in the work done so far. If I understand the intent of the task (and I'm not certain I do), you'll want to describe and/or script setting up a Postfix relayhost with authentication for sending *outgoing* email via a relay.
My recommendation (one of the other mentors please confirm) is to investigate "relayhost" and how you might set that up (with a script, or whatever) to use a gmail or other relay.
One of the mentors has sent this task back for more work. Talk to the mentor(s) assigned to this task to satisfy the requirements needed to complete this task, submit your work again and mark the task as complete once you re-submit your work.
Do you mean Rizzo?
Sorry, I didn't send the text I wrote.
On the one hand, I wanted to second him. Please investigate how to use the "relayhost" configuration option in postfix (I'm sorry we didn't say that explicitly in the task description) and how to use it with smtp authentication. You should write a small howto to configure postfix to do this. You don't have to finish the script if you do this.
On the other hand, if you don't want to write the tutorial, you should add some error handling to your script. What happens if the smtp connection times out? What happens if the server does not provide SSL? What happens if the server has an unknown or wrong certificate?
The work on this task is ready to be reviewed.
Ok, this looks even better. The RELAYING article was the one part of the task we mentioned.
I don't want to stretch this task too far, but could you please also insert a switch to either enable TLS or not? And maybe also add the possibility to use SSL, i.e. the connection is encrypted right from the beginning on, and not only after connecting to a plain-text host and issueing the which to use tls ("starttls")?
Apart from that, did you forget the README? You uploaded RELAYING twice, but you said in IRC you would upate the README as well.
After uploading the README, we will close this task (if you don't want to do the SSL part). But if we close it now, you couldn't upload further documents.
I meant that I would upload the RELAYING file not the README file.
I thought smtp_use_tls would enable it. If you don't mind, I have another task that I would like to claim so unless I sound too impatient could you close the task?
Congratulations, this task has been completed successfully.
