Should problems regarding the SMTP service arise, it is necessary to verify:
- SMTP PARAMETERS – parameters introduced in the SMTP SERVER ADDRESS, PORT, SMTP USER, SMTP PASSWORD fields must be correct and in particular coincide with those released by the service provider.
- SMTP SERVER STATUS – the SMTP server, through the TCP/IP communication protocols, must be reachable on the network at the IP address and port indicated. Therefore, check that the parameters entered during configuration in the SMTP SERVER tab are correct and in particular coincide with those released by the service provider. If the server in question is protected by a specific firewall, it is necessary to open the TCP/IP ports in accordance with the firewall rules to allow the server to be reached in any case.
- SMTP SERVICE STATUS – verify that the SMTP service is online and running.
