FB郵件伺服器測試smtp，pop3

測試是否支援smtp，pop3，imap，webmail。并且支援對應的SSL加密smtps，pop3s，imaps，https。

測試pop3

telnet localhost 110

Trying 127.0.0.1...

Connected to localhost.localdomain (127.0.0.1).

Escape character is '^]'.

+OK Hello there.

pass test

+OK logged in.

list

+OK POP3 clients that break here, they violate STD53.

.

quit

+OK Bye-bye.

Connection closed by foreign host.

測試smtp認證

通過以下指令獲得ppabc\@zhank.com的使用者名及密碼的BASE64編碼：

perl -e 'use MIME::Base64; print encode_base64("ppabc\@zhank.com")'

cHBhYmNAemhhbmsuY29t

perl -e 'use MIME::Base64; print encode_base64("111111")'

MTExMTEx

然後本機測試，其過程如下 

telnet localhost 25

220 mail.zhank.com ESMTP Postfix - by zhank.com

ehlo demo.domain.tld

250-mail.zhank.com

250-PIPELINING

250-SIZE 10240000

250-VRFY

250-ETRN

250-AUTH LOGIN PLAIN

250-AUTH=LOGIN PLAIN

250-ENHANCEDSTATUSCODES

250-8BITMIME

250 DSN

auth login

334 VXNlcm5hbWU6

334 UGFzc3dvcmQ6

235 2.7.0 Authentication successful

221 2.0.0 Bye

最後出現235 Authentication Successful 表明認證成功了。

測試smtps

mail# telnet localhost 25

Trying ::1...

220 mail.zhank.com ESMTP Postfix

ehlo localhost

250-STARTTLS

測試pop3s/imaps

telnet連接配接本機的993，995端口出現如下提示：

telnet localhost 993

telnet: connect to address ::1: Connection refused

telnet localhost 995
