I run FMS on a Mac OSX 10.11.3 and FMS 184.108.40.2063.
In the General Settings/Email notifications I enter the data to configure the email address, SMTP address and FMS tells me:
SMTP test failed: SMTPEmailSendFailed check the SMTP settings and email address.
I check it and everything is correct.
I tested it by putting this address and smtp in Mail and it works.
The only things which change is the port: 25 for FMS, 110 for Mail. But it should not be the problem.
Same problem with SSL or without.
Do you have any idea of the problem?
FMS works correctly even with clients connected from the web to an hosted file.
