telnetでsmtp(postfix) (telnet xxx.xxx.xxx.xxx 25) まずは基本中の基本から メモ
わすれちゃうんで、メモ
一番最初はDNS MXの確認
[hirasawa@ubunt1004-32-2 ~]$ nslookup > set type=mx > hirasawa.local Server: 192.168.1.28 Address: 192.168.1.28#53 hirasawa.local mail exchanger = 10 mail.hirasawa.local. > mail Server: 192.168.1.28 Address: 192.168.1.28#53 mail.hirasawa.local canonical name = cent5-64b-40.hirasawa.local. > quit Server: 192.168.1.28 Address: 192.168.1.28#53 ** server can't find quit: NXDOMAIN > exit [hirasawa@ubunt1004-32-2 ~]$
んで続いて、nmapでポートが開いていることを確認。
[hirasawa@ubunt1004-32-2 ~]$ nmap 192.168.1.40 | grep 25 25/tcp open smtp [hirasawa@ubunt1004-32-2 ~]$ [hirasawa@ubunt1004-32-2 ~]$ nmap localhost | grep 25 Warning: Hostname localhost resolves to 2 IPs. Using 127.0.0.1. [hirasawa@ubunt1004-32-2 ~]$
[hirasawa@ubunt1004-32-2 ~]$ telnet 192.168.1.40 25 Trying 192.168.1.40... Connected to 192.168.1.40. Escape character is '^]'. 220 cent5-64b-40.localdomain ESMTP Postfix HELO hirasawa.local 250 cent5-64b-40.localdomain MAIL from hiraawa@hirasawa.local 501 5.5.4 Syntax: MAIL FROM:<address> MAIL FROM: hirasawa@hirasawa.local 250 2.1.0 Ok RCPT TO: hirasawa@hirasawa.local 250 2.1.5 Ok DATA 354 End data with <CR><LF>.<CR><LF> From: hirasawa@hirasawa.local Subject 0753 Hello from ubu . 250 2.0.0 Ok: queued as 5CC721F0070F QUIT 221 2.0.0 Bye Connection closed by foreign host.

順番が逆になっちまうけど、
mail-server(192.168.1.40)で走ってるsmtpはpostfix
