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:
Code: 
@  IN  MX  10  server.c4.sysinst.ida.liu.se.

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:
Code: 
@    IN     TXT     “v=spf1 mx ip4:130.236.189.218 mx:server.c4.sysinst.ida.liu.se ~all”

But after I added that I'm not able to connect using telnet localhost 25 on the server. Help would be appreciated.
