Hi
I have problem with setting SMPT settings locally. I tried to set up these settings so that I can use email verification but when i enter all details and try to send test email it return me message

Unable to send email via JavaMailCould not connect to SMTP host: smtp.eu.mailgun.org, port: 25

and same settings use my colleague and it works when he test it.
I put host, port 25, username, password, security none, from address, from name but still getting this message that is unable to send and i don't see any problem if I have same settings as colleague.
