Get postfix working on ubuntu

[themightychris]

Can't get sendmail command to work, which PHP will need:

sudo hab pkg exec jarvus/postfix sendmail -c /hab/svc/postfix/config -i -v chris

Once that works, sendmail_path and sendmail_args can be set in php.ini, or we could create a wrapper script for binlinking so PHP config doesn't need to be changed

There seem to be issues with write permissions for some process in play for mail addressed to local users:

postfix/local[5758]: 7C2E023F578: to=<[email protected]>, orig_to=<chris>, relay=local, delay=9.4, delays=9.4/0.01/0/0.01, dsn=5.2.0, status=bounced (cannot update mailbox /hab/svc/postfix/data/spool/chris for user chris. unable to create lock file /hab/svc/postfix/data/spool/chris.lock: Permission denied)

but that shouldn't matter for remote

nc localhost 25 email to a remote gmail address gets delivered via mailgun

[themightychris]

Success!

hab pkg exec jarvus/postfix sendmail -C /hab/svc/postfix/config -i -v [email protected]

worked for remote delivery

hab pkg exec jarvus/postfix sendmail -C /hab/svc/postfix/config -i -v root

worked for local delivery AFTER manually chowning /hab/svc/postfix/data/spool/root to user root after seeing:

postfix/local[6482]: 81FED23F587: to=<[email protected]>, relay=local, delay=0.01, delays=0/0/0/0, dsn=4.2.0, status=deferred (cannot update mailbox /hab/svc/postfix/data/spool/root for user root. destination /hab/svc/postfix/data/spool/root is not owned by recipient)

Trying to deliver to other local users though results in

delivery via local: cannot update mailbox
    /hab/svc/postfix/data/spool/chris for user chris. unable to create lock
    file /hab/svc/postfix/data/spool/chris.lock: Permission denied

I tried to set sendmail_path to hab pkg exec jarvus/postfix sendmail -C /hab/svc/postfix/config in /etc/php/5.6/cli/php.ini and then this happens:

php > var_export(Emergence\Mailer\Mailer::send('[email protected]', 'Subject', date('c')));
sendmail: error: unauthorized configuration directory name: /hab/svc/postfix/config
sendmail: fatal: specify "alternate_config_directories = /hab/svc/postfix/config" or "multi_instance_directories = /hab/svc/postfix/config" in /etc/postfix/main.cf
false
php > echo ini_get('sendmail_path');
hab pkg exec jarvus/postfix sendmail -C /hab/svc/postfix/config

might be good to find a compile-time flag that lets us replace /etc/postfix with /hab/svc/postfix/config

materializing sendmail_path to /hab/pkgs/jarvus/postfix/3.2.4/20180104203932/bin/sendmail -C /hab/svc/postfix/config seems to help things, maybe using hab pkg exec was somehow still running the system version:

php > var_export(Emergence\Mailer\Mailer::send('[email protected]', 'Subject', date('c')));
sh: 1: /hab/svc/postfix/data/spool#: Permission denied
false
php > echo ini_get('sendmail_path');
/hab/svc/postfix/data/spool# /hab/pkgs/jarvus/postfix/3.2.4/20180104203932/bin/sendmail -C /hab/svc/postfix/config
