PhotoStore Documentation

Expected response code 250 but got code 530 - 530 5.7.0 Must issue a STARTTLS command first

When you get this error trying to send emails in PhotoStore 4 it usually means the SMTP you setup requires ssl. A popular example is using gmail smtp, they tell you to enter: for the server.
However in PhotoStore 4 (php based) you will need to specify that this requires SSL, so type it like: 

This will work on any system that requires SSL login to email system.
Just put ssl:// before the smpt server name.
