Anyone familiar with iconv errors during install? I got the following error log when trying my first Haraka install: http://pastebin.com/GhMGaeWW

Squeebee: do you have libiconv-dev installed? (I'm not sure if you need that, but maybe)

Does Haraka need Node 6? I may have more luck with the older release.

Squeebee: It doesn't require v6 to my knowledge. I think it works with some pretty old releases.

Ok thanks!

Squeebee: though if you can use 6.x, life is better under es6 (not for haraka necessarily, but for any new code you need to write =)

Good to know, thanks EyePulp!

Yeah we support v0.10 - v6

Ok, while I play with this, how would I set everything to route to a specific host/port? I'd like to start by sending everything to smtp-sink so it doesn't go anywhere.

use smtp_forward.

Thank you.

It's in the default config/plugins. Configuration docs are on the web site.

Found it, thanks.

And one more to get me started. Does Haraka support multiple outbound IPs, and if so how do I assign a message to its appropriate IP?

Yes, you have to write a custom plugin though, hooking the get_mx hook.

Ok, where do I configure the IPs?

http://haraka.github.io/manual/Outbound.html - scroll down to "The get_mx hook"

Basically you have to write some javascript for this. There's no default support for it.

Got it, this gives me enough context to start working it out.

Although if anyone has an example of a plugin they wrote to assign IP I wouldn't complain. ;)

Does Haraka log by default or does it require a plugin?

It logs to stdout by default.

(which is enough for some people)

e.g. I use runit to keep it alive, which loves logging to stdout.

Ok, otherwise I'm seeing log.syslog and log.elastisearch

and for stdout you can add timestamps if you need them.

Good to know, how do I add those?

echo 1 > config/log_timestamps

Thanks!

Ok I'm wondering how much work this would be: 1) Configure named pools of IPs, each with their own EHLO. 2) Assign a message to a pool (round robin within the pool) based on finding the name of the pool in an X header.

Trivial.

Don't even need an X-header. just use transaction.notes which is the same as hmail.todo.notes

Any chance of an example of that while I dig through the manual?

Ok, so transaction notes lets me store the name of the IP pool I want, and I'd populate it by grabbing transaction.header, then remove the header?

You need to be clearer on what you're trying to achieve.

You want the sender to define the outbound IP?

Ok, let's say I want to send transactional mail and newsletters, and that for transactional I have a pool named (oddly enough) "transactional" and the newsletters are named "newsletters". In the transactional pool is 192.168.1.10 and 192.168.1.20 and they have helo of mta1.foo.com and mta2.foo.com. In the newsletter pool is 192.168.2.10 and 192.168.2.20 and they have helo of mta1.bar.com and mta2.bar.com. I want to assign injected messages to transaction

Ultimately that may scale to hundreds of IPs in tens of pools, so getting it into a conf file is desirable.

Right but how should Haraka know which mail is which?

By From? By connecting IP?

Because the individual messages have a header called X-Pool (in this example) with the name of the pool to assign to.

OK, so just store that in transaction.notes

then in the get_mx hook just look at hmail.todo.notes.whatever_key_you_picked

Aah, so there's no explicit step to pull the header, that auto-populates?

no, you put that in your plugin.

in hook_data_post

Ok. So 1) Pull header content, stick it in notes, delete header. 2) Take pool name, assign it to pool. and I assum 0) Read a config file, store array of IPs with helo?

yup

Time to learn JavaScript then. I'll give it a go.

Do any of the existing plugins have bits and pieces of this to use as examples? (Reading and storing a conf, headers to notes, IP assignment)?

reading config is done by just about every plugin.

it's really easy.

the rest is all pretty simple frankly.

Well then I'll give it a go.
