PHP mac localhost 环境下发送邮件

转载自：http://mabblog.com/blog/2011/09/lion-smtp-postfix-relay-and-dreamhost/

When developing web-apps locally it is useful to have a fully functional smtp server to test automated emails associated with your application. Many times the network you are developing on will not allow you to simply start up postfix and and run your own local
smtp server. However, this doesn’t imply that you can’t use postfix – modifying postfix to relay all outgoing mail to an external / offsite smtp server that you have control of will enable you to develop & test the parts of your application that require a
local outgoing smtp server without an issue.

Many times port 25 (the default smtp port) will be blocked somewhere along the line in your network connection. You can figure out if your network configuration or ISP is blocking port 25 by running

telnet smtp.server.com 25.

Edit /etc/postfix/main.cf

relayhost = [mail.domain.com]:587

smtp_sasl_auth_enable = yes

smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd

smtp_sasl_security_options = noanonymous

smtp_use_tls = yes

Create/edit /etc/postfix/sasl_passwd

[mail.domain.com]:587 username@domain.com:password

Run this command in your shell once the above two files are created/modified:

sudo chmod 600 /etc/postfix/sasl_passwd

sudo postmap /etc/postfix/sasl_passwd

sudo launchctl stop org.postfix.master

sudo launchctl start org.postfix.master



# test postfix, cmd+d after typing message content to send message

mail -s "Testing, Testing" you@domain.com
