====== POP3, IMAP and SMTP AUTH for Popular Mail Clients ======

=== Introduction ===

SDF uses SMTP Authentication to allow remote network clients such as desktop, tablet and phone mail applications to use its SMTP server for the purpose of sending (relaying) e-mail messages. SDF users with the VPM, VHOST and MetaARPA memberships have access to the SMTP server.

==== Quick Starter Notes ====

=== Receiving Email ===

  * SDF's POP3 server address is **mx.sdf.org** port 110
  * SDF's IMAP server address is **mx.sdf.org** port 143 (993 for TLS/SSL)

=== Sending Email ===

  * SDF's SMTP server is **mx.sdf.org**
  * SDF's SMTP server listens on **port 25** as well as **ports 23, 53, 587 and 8080**. Some ISPs throttle or block activity on port 25.
  * Set your SMTP AUTH secret with **mkvpm set //secret//** at the shell. The auth secret is not your SDF password; plese do not set //secret// to your SDF password.
  * Your SMTP AUTH username is your **domain name@sdf.org** (ex. alan8r.sdf.org@sdf.org)
  * SMTP via **STARTTLS** is recommended. Some email clients may refer to STARTTLS as TLS. TLS/SSL is not STARTTLS.

Please note: the SMTP AUTH secret is set on the command line via mkvpm. The command history of the shell may keep the secret in the history file.

==== The Mail Client Configurations ====

Please note that BlueMail on Android does not support the correct password encryption algorithm, and therefore you cannot set up your SDF email account under BlueMail. The devs have been notified of this bug; if they do fix it, the instructions here will be updated.

===== Emacs (SMTPmail, Rmail, Gnus) =====

The GNU Emacs editor includes several subsystems for handling email, including:

  * **SMTPmail** for sending email,
  * **Rmail** for reading email,
  * **Gnus**, a news reader that can also be used for reading email.

(Normally, you would choose to read email in Emacs with //either// Rmail or Gnus and would only configure the email reader of your choice.)

Configuration for these subsystems varies depending on whether you are running Emacs **locally** on the SDF system that hosts your email spool or **remotely** on another system like your home PC.

In either case, configuration mainly takes the form of Emacs Lisp expressions added to the startup file (usually ‘~/.emacs’) on the system where you will run Emacs. Optionally, the file ‘~/.gnus’ can be used for Gnus configuration to reduce clutter in your main startup file.

=== Common Configuration ===

Set the following variables regardless of which email subsystems you will you and whether you will be accessing email locally or remotely.

<file config>
(setq
   user-full-name "<your full name>"
   user-mail-address "<your email address>")
</file>

===  Local Configuration ===

**WARNING:** If you use either Rmail or Gnus to read email locally on your SDF email host system, all messages in your email spool at the time you start Rmail or Gnus will be //removed// from the spool and transferred to the email reader's inbox. Make a backup of your email spool (‘/sdf/mail/<username>’) beforehand unless you are committed to handling your email with Rmail or Gnus.

<file config>
;; For SMTPmail ...

(setq send-mail-function 'sendmail-send-it)

;; For Rmail, no configuration is necessary for local access.

;; For Gnus ...

(setq gnus-secondary-select-methods '((nnml "")))
</file>

=== Remote Configuration ===

<file config>
;; For SMTPmail ...

(setq
   send-mail-function 'smtpmail-send-it
   smtpmail-default-smtp-server "mx.sdf.org"
   smtpmail-local-domain "sdf.org"
   smtpmail-smtp-service 587
   smtpmail-stream-type 'starttls)
(load-library "smtpmail")

;; For Rmail ...

(setq
   rmail-primary-inbox-list '("imaps://<username>:<password>@mx.sdf.org")
   rmail-preserve-inbox t)     ; (If you want to keep your mail in your SDF IMAP inbox.)

;; For Gnus ...

(add-to-list 'gnus-secondary-select-methods
  '(nnimap "mx.sdf.org"
    (nnimap-address "mx.sdf.org")
    (nnimap-server-port 143)
    (nnimap-stream starttls)))
</file>

Additionally, for remote access place the following lines in the file ‘~/.authinfo’ (or ‘~/.authinfo.gpg’ for encryption):

<file config>
machine mx.sdf.org port 587 login <mkvpm domain>@sdf.org password <mkvpm secret>
machine mx.sdf.org port 143 login <username> password <password>
</file>

==== Email Commands ====

After you have completed the configuration, start or restart Emacs and use the following commands to access your email:

^ description ^ //command// ^
| SMTPmail: | ''C-x m'' |
| Rmail: | ''M-x rmail'' |
| Gnus: | ''M-x gnus'' |

===== K-9 Mail for Android =====

^ To //retrieve// mail via IMAP ^^
| imap server | ''mx.sdf.org'' |
| Security | ''SSL/TLS'' |
| Port | ''993'' |
| Username | //sdf user name (eg, alan8r)// |
| Authentication | ''Normal password'' |
| Password | //password associated with sdf user above// |

^ To //send// mail, set up SMTP with ^^
| SMTP server | ''mx.sdf.org'' |
| Security | ''STARTTLS'' |
| Port | ''587'' |
| Username | //Your domain name//* |
| Authentication | ''Encrypted password'' |
| Password | //string set via "mkvpm set YOUR_PASSWORD_HERE"// |
  * If you are a Meta-ARPA member and //not// a VHOST member, this is whatever web domain you've chosen (frequently username.sdf.org@sdf.org). If you're a VHOST member, it's your VHOST domain. 

===== Outlook Express under Windows =====

  * Open Outlook Express
  * Tool -> Accounts
  * Click Add -> Mail to start the Account Wizard
  * Display name: Your Name
  * E-Mail address: Your email address (ex. bill@microsoft.com)
  * Select POP3

===== Heirloom Mailx under Linux/BSD =====
  
Add the following to ~homeuser/.nailrc to set the default SMTP relay:

<code>
# Remote SDF SMTP relaying (use SDF 'mkvpm' tool to set auth user:pw):
set ssl-verify="ignore"
set smtp-use-starttls
set smtp=mx.sdf.org:587
set smtp-auth=cram-md5
set smtp-auth-user="sdf_user.sdf.org@sdf.org"
set smtp-auth-password="my_password"
</code>

The SDF CA is self-signed but can still be used if desired. Retrieve and store somewhere (ie. under ~/.openssl/) as pem file, then edit ~homeuser/.nailrc like so:

<code>
set ssl-ca-file="/home/home_user/.openssl/sdf_self-signed_ca.pem"
set ssl-verify="warn"  # will issue "self-signed CA" warning
...
</code>

Account-specific smtp settings are possible; see the Heirloom Mailx documentation.

===== Postfix MTA using libsaslc(3) on NetBSD 6.x: =====

  * first, verify that //postfix(1)// knows about //libsaslc// :

<code>
% sudo postconf -A
saslc
</code>

  * create (as superuser) the following postfix config files:

///etc/postfix/main.cf//

<code>
myhostname = mypc.my.box
mydomain = my.box
mynetworks_style = host
alias_maps = hash:/etc/mail/aliases
# SMTP client settings:
relayhost = [mx.sdf.org]:submission
smtp_generic_maps = hash:/etc/postfix/generic
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options = noplaintext, noanonymous
smtp_sasl_tls_security_options = noanonymous
## explicitly allow/prohibit certain SSL protocols:
#smtp_tls_mandatory_protocols = !SSLv2, !SSLv3, TLSv1
## use of "may" option allows fallback to cleartext
#smtp_tls_security_level = may
smtp_tls_security_level = encrypt
smtp_sasl_type = saslc
</code>

///etc/postfix/generic//

<code>
# applies to msgs to be delivered off-site
me@mypc.my.box  sdf_login@sdf.org
</code>

///etc/postfix/sasl_passwd//
(for security set ownership to ''root:wheel'', permissions to ''600'')

<code>
[mx.sdf.org]:submission  sdf_login.sdf.org:smtp_passwd
</code>

  * hash ///etc/postfix/{generic,sasl_passwd}, then check and reload configs//:

<code>
% cd /etc/postfix/
% sudo postmap generic sasl_passwd  # creates generic.db & sasl_passwd.db
% sudo postfix check                # no output unless errors
% sudo /etc/rc.d/postfix reload
</code>

  * test to verify everything is working correctly:

<code>
% mailx sdf_login@sdf.org
  Subject: test
  123
  .
  EOT

% sudo tail -n10 /var/log/maillog | grep smtp
  Apr 27 08:53:42 mypc postfix/smtp[13387]: A61631F1FDC: to=<sdf_login@sdf.org>, \
  relay=mx.sdf.org[192.94.73.24]:587, delay=3.9, delays=0.02/0/3.7/0.11, dsn=2.0.0, status=sent \
  (250 2.0.0 s3RFrfvZ010436 Message accepted for delivery)
</code>

You should now be set up to use SDF's SMTP server. Enjoy!
