I have a problems receiving and sending emails from and to externals users. However I don't have this problem with the emails receiving and sending between my coworkers (we have the same domain @spectratech.gr). We checked the SMTP settings (IMAP/POP3), SSL/TLS settings, updates and these setting seems to be ok. What could be the problem? thank you

Sending among coworkers is sending from one domain to itself. When sending to other domains, there will always be a higher possibility that one or more of them may flag your domain for security shortfalls that are not identified within the host domain. This could happen for many reasons, such as IP address, server security setup, and more.
