netizen_69 New Member Hi there, I'm new to this. I'm trying to learn to setup a Linux E-mail server. Printed telnet connection closed by foreign host linux out the "The Perfect Setup - Fedora Core 5 (64 telnet connection closed by foreign host ubuntu Bit)" I faced the foolowing message when I tried to telnet to see if SMTP-AUTH and connection closed by foreign host cisco TLS work properly.

How did you start postfix? Does postfix log anything of note when it first starts up? –larsks Feb 13 '12 at 14:41 Installed via ports? Did you allow the service in /etc/rc.conf? If you have not allowed the service, did you run as a runone instance? Did you use /usr/local/etc/rc.d/ to start the services? –Tim Feb 13 '12 at 14:48 Installed trough ports started using postfix start –FLY Feb 13 '12 at 15:39 also I

When I connect to it, I get Trying 157.56.195.250... Connected to imap-mail.outlook.com. Escape character is '^]'. And I can enter a command. Whenever I enter seemingly anything, it disconnects me saying: Connection closed by foreign host. I'm trying to determine (or even venture a guess as to) the reason and I don't know enough about telnet to even make an educated guess. Can anyone point me in the right direction? For the record, I'm able to connect a desktop mail client to this address and it works fine. The machine I'm trying from is on the same network running CentOS 6 with no firewall rules whatsoever, which clearly isn't the problem anyway. centos telnet share|improve this question edited Nov 19 '14 at 2:17 jasonwryan 35k984133 asked Nov 18 '14 at 23:45 JamesB41 10814 What commands did you try to enter? Have you compared that with what your software sends? The most obvious reason would be that you entered an invalid command, and you've given us no reason to rule that out. –Gilles Nov 19 '14 at 1:09 add a comment| 1 Answer 1 active oldest votes up vote 3 down vote accepted The host probably expects SSL. You must use openssl instead of telnet: openssl s_client -connect imap-mail.outlook.com:993 -crlf share|improve this answer edited Nov 19 '14 at 1:47 answered Nov 19 '14 at 0:12 Hauke Laging
