npm install eelmailemail server providing imap
and smtp
Let's set up an email server that sounds like a fun thing to do why not.
We can start a server as root so that it can listen on low ports (25 and 143)
used by smtp and imap:
``
$ sudo eelmail server -d ./maildb
This isn't so great for security, so you probably want to drop privileges
inside the server with --uid and --gid:
`
$ sudo eelmail server -d ./maildb --uid=$UID --gid=$GROUPS
Once the server is running, create a user account:
`
$ eelmail -d ./maildb users create substack \
--login.basic.username=substack --login.basic.password=beepboop
You can also pass in the datadir with $EELMAIL_DATADIR.
If it worked, eelmail users list should now show your username:
`
$ eelmail users list
substack
Repeat for additional user accounts you wish to configure.
Now that the server is running and accounts are configured, let's send a test
email. Here I'm using substack.net but you should replace that with your own domain.
Make sure you have netcat installed then do:
`
$ nc substack.net 25 <
> mail from: alice@arpa.mil
> rcpt to: substack@substack.net
> data
> subject: yo
>
> beep boop
> .
> quit
> END
220 beep
250 localhost
250
250
354
250
221 Bye!
Now make sure you have an email server (like postfix on linux) running locally and do:
`
$ fetchmail -p imap -u substack substack.net
Enter password for substack@substack.net:
1 message for substack at substack.net.
reading message substack@substack.net:1 of 1 (17 header octets) (9 body octets) flushed
Enter the password that you configured and if it worked, you should now have
mail in your local inbox.
Type mail to read your email:
`
$ mail
"/var/mail/substack": 1 message 1 new
>N 1 substack@substack.net Fri Sep 26 09:51 18/728 yo

You can also create your own server from the api:
` js
var eelmail = require('eelmail');
var level = require('level-party');
var db = level('./data/db');
var em = eelmail(db, { dir: './data' });
em.createServer('smtp').listen(25);
em.createServer('imap').listen(143);
`
Here we use level-party so that the user accounts can be modified while theeelmail users
server is running with the command. Just make sure that -d
matches the data dir.
`
Usage: eelmail COMMAND...
eelmail {OPTIONS} users ...
Manage eelmail user accounts.
Run eelmail users -h for the list of commands.
eelmail server {OPTIONS}
Start an imap and smtp server.
--ports.smtp port to use for smtp (default: 25)
--ports.imap port to use for imap (default: 143)
To use ssl for imap, specify one of:
--imap.cert / --imap.key paths of tls cert and key files
--imap.pfx path of pfx file
eelmail help
Show this message.
Global options:
-d, --dir directory to use to store data
default: $EELMAIL_DATADIR or ./eelmail.db
`
` js`
var eelmail = require('eelmail')
Create an eelmail instance em from a db and opts.
Create a server for type:
* 'imap' - service to fetch saved emails'imaps'
* - imap over ssl'smtp'
* - service to receive emails'smtps'
* - smtp over ssl
For 'imaps', 'smtp', and 'smtps' you'll need to supplyopts.key/opts.cert or opts.pfx.
Close the database.
With npm, to get the eelmail command, do:
`
npm install -g eelmail
and to get the library, do:
`
npm install eelmail
