MAMP Pro

Mail

If you try to send a mail with MAMP Pro you will notice that this is not working out-of-the-box. MAMP Pro uses postfix as you can find on the last tab of the MAMP Pro app.

• Just fill in 'gmail.com' at the Domain of outgoing mail and restart the server.
• Now open the mail log file which is located in the /var/log directory and you will see:

May 28 16:09:39 Harms-MBP-3.fritz.box postfix/master[78220]: fatal: bind fe80::1 port 25: Can't assign requested address
May 28 16:09:49 Harms-MBP-3.fritz.box postfix/master[78221]: fatal: bind fe80::1 port 25: Can't assign requested address

The reason of these errors is located in the wrong binding to the ipv6 instead of the ipv4.

To change this:

• Edit the file main.cf located in the /etc/postfix/main.cf in terminal.
• Type

  $ sudo nano /etc/postfix/main.cf

• Add the line

  inet_protocols = ipv4

• Save the file in nano.
• Stop postfix:

   sudo launchctl stop org.postfix.master

• Start postfix:

   sudo launchctl start org.postfix.master

• Now look in the mail.log

  tail -f -n 65 /var/log/mail.log

• Resulting in

May 28 16:28:29 Harms-MBP-3.fritz.box postfix/master[78439]: fatal: bind fe80::1 port 25: Can't assign requested address
