Postfix
|
|
=======
|
|
|
|
Postfix is full featured MTA (Message Transfer Agent). Here we will configure it in smarthost mode as part of common [Mutt](/doc/mutt/)+Postfix+[Fetchmail](/doc/fetchmail/) stack.
|
|
|
|
Installation
|
|
------------
|
|
|
|
`dnf install postfix procmail make cyrus-sasl cyrus-sasl-plain`
|
|
|
|
Cyrus-sasl is installed to authenticate to remote servers. Procmail is not strictly necessary, but is useful to sort your incoming mail, for example to put each mailing list in its own directory. Make is also not necessary, but is used to keep Postfix lookup tables.
|
|
|
|
You should also check `alternatives` command, to see if it is the default `mta`. It probably is not. You may need to `dnf remove ssmtp` or something
|
|
|
|
Configuration
|
|
-------------
|
|
|
|
In TemplateVM open `/etc/aliases` and add line:
|
|
|
|
~~~
|
|
root: user
|
|
~~~
|
|
|
|
and run `newaliases`.
|
|
|
|
This is the only thing to do in TemplateVM, as MTA configuration is AppVM specific, so we will keep it in `/usr/local` (ie. `/rw/usrlocal`) in each AppVM.
|
|
|
|
Now shutdown TemplateVM, start AppVM. Create directory `/usr/local/etc/postfix` and copy `/etc/postfix/master.cf` and `/etc/postfix/postfix-files` there.
|
|
|
|
### Makefile
|
|
|
|
Postfix keeps its lookup tables in bdb hash databases. They need to be compiled from source files. Postfix admins like to keep track of them by means of `/usr/local/etc/postfix/Makefile`:
|
|
|
|
~~~
|
|
all: $(addsuffix .db,$(shell sed -n -e '/^[^#].*hash:\/etc\/postfix/s:.*/::p' main.cf))
|
|
newaliases
|
|
clean:
|
|
$(RM) *.db
|
|
.PHONY: all clean
|
|
|
|
%.db: %
|
|
/usr/sbin/postmap hash:$<
|
|
~~~
|
|
|
|
### Postfix main configuration
|
|
|
|
`/usr/local/etc/postfix/main.cf` (`/etc/postfix` is intentional, don't correct it):
|
|
|
|
~~~
|
|
mydestination = $myhostname, $myhostname.$mydomain, $myhostname.localdomain, localhost, localhost.$mydomain, localhost.localdomain, $mydomain, localdomain
|
|
mynetworks_style = host
|
|
|
|
inet_protocols = ipv4
|
|
|
|
smtp_generic_maps = hash:/etc/postfix/generic
|
|
local_header_rewrite_clients =
|
|
|
|
smtp_sender_dependent_authentication = yes
|
|
sender_dependent_relayhost_maps = hash:/etc/postfix/sender_relay
|
|
smtp_sasl_auth_enable = yes
|
|
smtp_sasl_password_maps = hash:/etc/postfix/saslpass
|
|
smtp_sasl_security_options =
|
|
smtp_tls_security_level = encrypt
|
|
smtp_sasl_mechanism_filter = plain, login
|
|
smtpd_relay_restrictions = permit_mynetworks,permit_sasl_authenticated,defer_unauth_destination
|
|
smtpd_sender_restrictions = check_sender_access hash:/etc/postfix/sender_access
|
|
|
|
home_mailbox = .maildir/
|
|
setgid_group = postdrop
|
|
mail_owner = postfix
|
|
|
|
html_directory = no
|
|
manpage_directory = /usr/share/man
|
|
queue_directory = /var/spool/postfix
|
|
readme_directory = no
|
|
|
|
mailbox_command = /usr/bin/procmail
|
|
sendmail_path = /usr/sbin/sendmail
|
|
newaliases_path = /usr/bin/newaliases
|
|
mailq_path = /usr/bin/mailq
|
|
alias_maps = hash:/etc/aliases
|
|
~~~
|
|
|
|
### Lookup tables
|
|
|
|
`/usr/local/etc/postfix/generic` (put there your primary address):
|
|
|
|
~~~
|
|
@localhost your.mail@example.com
|
|
~~~
|
|
|
|
`/usr/local/etc/postfix/sender_relay`. This is an important file. Put all your SMTP servers there. Pay attention to port (smtp/submission). Square brackets have their special meaning, they are almost certainly needed. For more info consult Postfix manual.
|
|
|
|
~~~
|
|
your.mail@exmaple.com [mail.example.com]:submission
|
|
your.other@mail.com [smtp.mail.com]:smtp
|
|
~~~
|
|
|
|
`/usr/local/etc/postfix/saslpass`. Here you put passwords to above mentioned servers. It depends on your provider if you need to put whole email as username or just the part before `@`.
|
|
|
|
~~~
|
|
[mail.example.com]:submission your.mail:y0urP4ssw0rd
|
|
[smtp.mail.com]:smtp your.other@mail.com:supers3cret
|
|
~~~
|
|
|
|
`/usr/local/etc/postfix/sender_access`. I use it to nullroute known spam domains. If you do not need it, comment respective line in `main.cf`.
|
|
|
|
~~~
|
|
spamdomain1.com DISCARD
|
|
spamdomain2.com DISCARD
|
|
~~~
|
|
|
|
Now run `make` in `/usr/local/etc/postfix`. It will hopefully compile four above mentioned lookup tables (`generic.db`, `sender_relay.db`, `saslpass.db` and `sender_access`).
|
|
|
|
### procmail
|
|
|
|
Don't start postfix or fetchmail yet, first create `/home/user/.procmailrc`:
|
|
|
|
~~~
|
|
MAILDIR = "${HOME}/.maildir"
|
|
ORGMAIL = "${MAILDIR}/"
|
|
DEFAULT = "${MAILDIR}/"
|
|
|
|
:0
|
|
* ^List-Id:.*qubes-users\.googlegroups\.com
|
|
list/qubes-users/
|
|
|
|
:0
|
|
* ^List-Id:.*qubes-devel\.googlegroups\.com
|
|
list/qubes-devel/
|
|
~~~
|
|
|
|
Run
|
|
---
|
|
|
|
Open `/rw/config/rc.local` and add those two lines (before fetchmail lines, if you have them):
|
|
|
|
~~~
|
|
#!/bin/sh
|
|
|
|
mount --bind /usr/local/etc/postfix /etc/postfix
|
|
systemctl --no-block start postfix
|
|
~~~
|
|
|
|
Make sure `/rw/config/rc.local` is executable (i.e., `chmod a+x /rw/config/rc.local`). Reboot your AppVM and you are done.
