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.
