Mail reception
How does SX-GATE receive emails from the Internet
The common way to retrieve incoming emails is by collecting them from a POP server.
If SX-GATE is connected to the Internet using a dial-up line with fixed IP address, the
ETRN protocol might be used as well. On a leased line and maybe also on an ISDN
dial-up line with fixed IP and callback, SX-GATE can be addressed anytime by any mail
server in the Internet. In these cases you might receive incoming emails directly with the
SMTP protocol. If in doubt, please ask your provider how you receive incoming emails.

Firewall access for SMTP
SMTP access to SX-GATE on interface
…
Accepting SMTP connections from the Internet usually requires a modification of the
firewall policy. If no modification is necessary, an appropriate message will be shown.
Else you can define firewall rules here. If there are no rules in the list, no inbound SMTP
connections will be accepted.
This wizard will check and configure the firewall policy of
the current Internet interface only. Depending on the firewall
configuration of other interfaces, it might be necessary to change
the firewall policy of these interfaces as well.
