#READING MAIL
#
#To read mail on Plan 9, you currently need a Plan 9 system that runs
#an SMTP server and spools your messages; attempting to read messages
#from a mounted Unix or NFS file system will not work, as Plan 9 uses
#different mechanisms to lock mailboxes.
#
#There are a few ways around this, though; upas/fs (see upasfs(4))
#can present POP3 and IMAP4 accounts as well as normal mail files. To
#use it, start upas/fs with the -f option specifying the "virtual"
#mail file to use. For example,
#
#! upas/fs -f/pop/your.host
#
#Other access methods (instead of "pop") include apop, poptls, and
#apoptls, imap, and imaps. If you use POP via SSL on port 995, you
#should use "pops" instead of "poptls".
#
#The appropriate Factotum key to be used is for example:
#
#! ; auth/factotum -g 'proto=pass dom=pop.gmx.de service=pop user=$your_username !password?'
#
#for POP3.
#
#To use the TLS-enabled access methods to a Plan 9 mail server
#(poptls, apoptls, and imaps) you need to generate a certificate and
#key for your mail server and tell the factotum of the server about
#that key:
#
#You can also use the [using ssl] page, for detailed instructions.
#! Login to a unix box with openssl installed (or install /n/sources/contrib/fgb/openssl.tgz) and generate the cert:
#! unix$ openssl req -x509 -nodes -newkey rsa:1024 -keyout key.pem -out cert.pem
#!
#! Logout and copy the files back to your mail server
#! ; cp /n/unix/.../cert.pem /sys/lib/tls/imap.pem
#! ; cp /n/unix/.../key.pem /sys/lib/tls/key.pem
#!
#(I think the plan9 tools do a much better job with this, e.g. for
#tlssrv, what is needed:
#! auth/rsagen -t 'service=tls role=client owner=*' > /sys/lib/tls/key
#! auth/rsa2x509 'C=FR CN=*.fakedom.dom' key | auth/pemencode CERTIFICATE > /sys/lib/tls/cert
#where FR is a two digit country code, and fakedom.dom is the fully
#qualified domainname.)
#!
#! Tell your factotum about the new key...
#! ; ramfs
#! ; cd /tmp
#! ; auth/secstore -g factotum
#! ; auth/secretpem /sys/lib/tls/key.pem >> factotum
#! ; auth/secstore -p factotum
#! You may also write factotum to /mnt/factotum/ctl
#! Exit this shell to destory the /tmp ramfs that has your keys in.
#!
#
#Then you must add your mail server's fingerprint to
#/sys/lib/tls/mail.
#
#If you are connecting to a third party mail server which is already
#set up for TLS authentication, you only need to teach Plan 9 about
#the fingerprint of its certificate.
#
#The easiest way to get the fingerprint is to run
#
#! ; upas/fs -f /imaps/your.host
#
#(instead of imaps you may be using poptls or apoptls) and look at
#the error message, something like
#
#! upas/fs pop3: server certificate 22471E10D5C1E41768048EF5567B27F532F33 not recognized
#! upas/fs: opening mailbox: bad server certificate
#
#To add this certificate type:
#
#! ; echo 'x509 sha1=22471E10D5C1E41768048EF5567B27F532F33' > /sys/lib/tls/mail
#
#If you are going to run an SMTP server, you should edit the files
#/mail/lib/smtpd.conf and /mail/lib/blocked to configure it. In
#addition, you should ensure that /mail/tmp exists and is world
#writeable (0777) if you want to receive emails larger than 64k.
#
#Looking in the other direction, Plan 9 comes with POP3 and IMAP4
#servers.
#
#SENDING MAIL
#
#To send mail from Plan 9, you need to configure the outgoing mailer;
#its main configuration file is /mail/lib/rewrite, which is supplied
#as an empty file. The manual rewrite(6) is worth reading. You'll
#want to start by copying either rewrite.gateway or rewrite.direct
#from the same directory and editing it to suit. Setting the smtp=
#attribute in your network database (file /lib/ndb/local) is all that
#is necessary to use rewrite.gateway, which sends all mail containing
#an @ sign to your local mail gateway. Mail to unqualified names
#(names without @somewhere) will still be delivered to local
#mailboxes. If you would like all mail to unqualified names to have a
#default domain added, start with rewrite.direct and edit to suit.
#
#The last rule in the rewrite files calls /mail/lib/qmail, which both
#queues the message and starts a daemon to try to deliver the
#messages currently in the queue (see qer(8) for more details). On
#systems not always connected to the internet, you may wish to use
#/mail/lib/justqmail instead, which only queues the message, and does
#not start a delivery daemon. When you are connected to the internet
#or your mail gateway, you can run /mail/lib/kickqueue to have the
#daemon try to send mail.
#
#If things aren't going right, look in /sys/log (mail smtp smtp.fail
#runq) are of interest.
#
#/mail/lib/remotemail, which actually delivers mail via SMTP,
#contains a default domain name used for unqualified outgoing mail;
#you will want to change it from yourdomain.dom to something more
#appropriate. If your SMTP-Server uses SMTP-AUTH to authenticate, add
#the "-a" flag to the upas/smtp-command (see smtp(8)). Also, note
#that you need to add your login information to factotum(4):
#
#! ; auth/factotum -g 'proto=pass service=smtp user=$your_username server=$the_addr_of_your_smtpserver !password?'
#
#Each local user has a mail directory /mail/box/$user; among other
#things, it usually contains a mailbox and a headers file
#/mail/box/$user/headers; the contents of the latter are included in
#all outgoing messages from that user. To add a ``full name'' field
#to your outgoing mail, add
#
#! From: "Glenda" <glenda@myserver.dom>
#
#If you wish to dynamically change your source domain (eg for
#laptops) the upasname environment variable can be set before
#executing the mail command; This ignores From: names set in
#/mail/box/$user/headers. EG
#
#! upasname=janet@machine.dom mail fred@machine.edu
#
#SMTP TLS AUTH
#
#Like the situation described above, you need to get the servers
#certificate fingerprint and add it to the list of authorised
#fingerprints, for smtp this time.
#
#Try to send email to the server:
#
#! ;upas/smtp -d -a -h mymachine.dom net!smtp.myserver.dom account-on-server dest-user@sest-system.dom
#
#this will probably fail with:
#
#! 220 2.0.0 Ready to start TLS
#! Wed Dec 1 13:52:01 GMT 2004 connect to net!smtp.server.dom:
#! 220 2.0.0 Ready to start TLS
#! errors Permanent Failure
#! QUIT
#! exits Permanent Failure
#
#now check /sys/log/smtp for the fingerprint
#
#! ; tail -1 /sys/log/smtp
#! felix Dec 1 14:17:56 remote cert. has bad thumbprint: x509 sha1=CE3C0D3BDA4B44A353C59EA665B7F8C109714341 server=smtp.server.dom
#
#and install this fingerprint for smtp
#
#! echo 'x509 sha1=CE3C0D3BDA4B44A353C59EA665B7F8C109714341' >> /sys/lib/tls/smtp
#
#PROBLEMS
#
#Some SMTP servers refuse to accept mail from clients that don't
#supply fully qualified domain names when authenticating (HELO or
#EHLO messages) - an anti-spam measure.
#
#This name is generated from either the site enviroment var, or if
#that is not set, by appending the sending machines domain to its
#system name. The domain is picked up from the dom= attribute from
#/lib/ndb/local.
