email-sender can not connect to server, does it use the same port number that the 3cx pbx use when it is loaded for email notifications?

Actual it is not the port that is the problem, if the password is numeric does this have an issue as I used a none numeric password and successfully sent it but when trying to using a numeric password whether assigned to a variable or within the password field of the email-sender it will not connect?

Does your password start with the number 0? If it does, remember that you must quote it, otherwise it will be treated as number, and then converted to string, and if it has a trailing 0, it will be removed.

Let me know if this is your case. Otherwise, please tell me how are you exactly configuring it, so we try to reproduce it here.
