Hi I have a Postfix mail server in a Debian Linux network and used to be able to connect to it on port 25 via telnet. I also have working DNS on the server.
I added this MX record to the DNS zone file:
It worked fine after that also but then I added this SPF record, the goal is that only the server is supposed to be able to send mail from the nework:
But after I added that I'm not able to connect using telnet localhost 25 on the server. Help would be appreciated.

mconnect
mconnect(1) User Commands mconnect(1)NAME
mconnect - connect to SMTP mail server socket
SYNOPSIS
mconnect [-p port] [-r] [hostname]
DESCRIPTION
The mconnect utility opens a connection to the mail server on a given host, so that it can be tested independently of all other mail soft-
ware. If no host is given, the connection is made to the local host. Servers expect to speak the Simple Mail Transfer Protocol (SMTP) on
this connection. Exit by typing the quit command. Typing EOF sends an end of file to the server. An interrupt closes the connection immedi-
ately and exits.
OPTIONS
The following options are supported:
-p port Specify the port number instead of the default SMTP port (number 25) as the next argument.
-r "Raw" mode: disable the default line buffering and input handling. This produces an effect similar to telnet(1) to port
number 25.
OPERANDS
The following operand is supported:
hostname The name of a given host.
USAGE
The mconnect command is IPv6-enabled. See ip6(7P).
