MailHog doesn't catch emails sent by PHP

[MblKiTA]

$ php -r "mail('test@test.com', 'test', 'test');"
2015/12/09 16:44:17 Using in-memory storage
2015/12/09 16:44:17 [SMTP] Binding to address: 0.0.0.0:1025
2015/12/09 16:44:17 [SMTP] Error listening on socket: listen tcp 0.0.0.0:1025: bind: address already in use

Fixed this by installing ssmtp and updating /etc/php5/cli/conf.d/zzzz_custom.ini to:
;sendmail_path='/usr/local/bin/mailhog'
sendmail_path='/usr/sbin/ssmtp -t'

/etc/ssmtp/ssmtp.conf:
...
mailhub=localhost:1025
...

Possibly there are better ways but this one worked for me.

My config.yml:

;sendmail_path='/usr/local/bin/mailhog'

You actually want this to be

sendmail_path='/usr/local/bin/mailhog sendmail foo@example.com'

FYI for others looking for why MailHog may not be catching Php SMTP emails.

check your ports! if you are using a Mail::factory or other class for SMTP emails, then it may default to port 25. MailHog configuration defaults to port 1025.

@Artistan thanks.

basically:

1. standard puphpet setup (mid 2017)
2. vagrant ssh; sudo apt-get install postfix; confirm all defaults (use tab/arrows, enter to navigate)
3. set your app's smtp port to 1025 for local testing
4. send a mail via some form or other means that will go via smtp/sendmail 1025
5. yourlocaldomain.dev:1025

I am used to CakePHP3 (where things are a bit easier to decipher) and this way I could test Zend Framework sendmail contact forms.
