Receiving mail securely on port 465 for Android clients

Android devices don’t seem to like STARTTLS on port 25 for security reasons. Maybe this can be fixed by importing a certificate, but before we were connecting on port 465 (smtps), so we will do this again. But sometime let’s check whether importing a certificate will allow STARTLTS on port 25 to work OK.

Create new certificates:

# rm /etc/exim/exim.key /etc/exim/exim.crt
# bash /usr/share/doc/exim4-base/examples/exim-gencert

Enable port 465 in /etc/default/exim4

SMTPLISTENEROPTIONS='-oX 465:25 -oP /var/run/exim4/exim.pid'

Restart exim.

Now the outgoing mail setup on Android works.

Dovecot

Copy across the dovecot configuration.

Remove old certificates and create new ones:

# rm /etc/dovecot/dovecot.pem  /etc/dovecot/private/dovecot.pem

Edit /usr/share/dovecot/dovecot-openssl.cnf appropriately, then

# cd /usr/share/dovecot/
# ./mkcert.sh
Generating a 2048 bit RSA private key
.......+++
..............................................+++
writing new private key to '/etc/dovecot/private/dovecot.pem'
.......

subject= /O=Dovecot mail server/OU=dovecot/CN=disruptive/emailAddress=roger@disruptive.org.uk
SHA1 Fingerprint=52:7D:4E:AE:7D:2D:E4:A6:4C:8B:31:93:DE:1D:21:1A:D0:9B:72:AE

Check that we are listening on port 993.

Android incoming imap connection now works.

Install spamassassin (new).

Previously we were using bogofiler — not very effective any more

# apt-get install spamassassin
# apt-get install exim4-daemon-heavy

(The package exim4-daemon-heavy replaces the "smaller" version of exim). OK - if we are calling spamassassin from procmail, this is not necessary. but for other possible configurations it might be.

Edit exim4.conf.template and uncomment:

spamd_address = 127.0.0.1 783

Then:

# update-exim4.conf

Then we want to call smapassassin from procmail.

in ~/.procmailrc

Trying this, from http://www.stearns.org/doc/spamassassin-setup.current.html

:0fw: spamassassin.lock
| /usr/bin/spamc

:0:
* ^X-Spam-Level: \*\*\*\*\*\*\*\*\*\*
zzzSPAM

:0:
* ^X-Spam-Status: Yes
zzzSPAM

Now incoming mails delivered to ~/Mail/ have spam headers and information added, and if spam are filed according to the above into ~/Mail/zzzSPAM.
