I signed up for a trial account on mailbox.org to see if I can use it in automated ecommerce process (tickets, customer notifications).
I found in the documentation that it's possible to use POP3/IMAP/SMTP. So far my tests were unsucessfull. Is it because the account is in "trial" mode? Or it just doesn't work?
This is not password/port/other setting issue. Neither it's the system issue - it was sucessfully tested with gmail.
