I try to setup SMTP Mail for my osTicket System for outgoing Alerts.
It doesn't matter which configuration I will use, it's always the error SMTP: Failed to connect socket: Connection times out.
My Configuration for now is:
SMTP Host: smtp.1und1.de
SMTP Port: 25
Auth Req: Yes
Credentials are correct, testet them multiple times. Even if I try to use SSL SMTP it's not working with port 465 or 587.
Do I need to setup any other configuration before? Edit a file?
Webhost by "1und1", with php 5.4, mysql 5.1 and domain
osTicket Version 1.7 and 1.8 both not working.
The E-Mail Adress is from 1und1 as well.
Thanks for Help.
