這個 script 是使用 expect 作的，也需要 telnet 指令
基本上就是用 telnet 驗證有沒有這樣子而已
編輯 check_email_verify.exp 檔，內容如下
#!/usr/bin/expect # # 檢查 email 存不存在 # need expect and telnet command # set timeout 60 set mx [lindex $argv 0] set em [lindex $argv 1] spawn telnet $mx 25 expect "220" send "EHLO $mx\n" expect "250 " send "MAIL FROM: <$em>\n" send "RCPT TO: <$em>\n" expect -re "450|550|2.1.5|ecipient.*ok" send "QUIT\n"
執行如下指令
mailserver 帳號 expect check_email_verify.exp mail.ssorc.tw [email protected]
成功的話就會是這樣子
spawn telnet mail.ssorc.tw 25 Trying xx.xx.xx.xx... Connected to mail.ssorc.tw. Escape character is '^]'. 220 XXXXXXXXX EHLO mail.ssorc.tw 250-XXXXXXXXX Hello [xx.xx.xx.xx] 250-SIZE 250-PIPELINING 250-DSN 250-ENHANCEDSTATUSCODES 250-STARTTLS 250-X-ANONYMOUSTLS 250-AUTH NTLM 250-X-EXPS GSSAPI NTLM 250-8BITMIME 250-BINARYMIME 250-CHUNKING 250-XEXCH50 250-XRDST 250 XSHADOW MAIL FROM: <[email protected]> RCPT TO: <[email protected]> 250 2.1.0 Sender OK 250 2.1.5 Recipient OK
有找到一個網頁 http://verify-email.org/ 也可以作這種事
MX record about ssorc.tw exists. Connection succeeded to mail.ssorc.tw SMTP. 220 XXXXXXXXX > HELO verify-email.org 250 ssorc.tw Hello [verify-email.org] > MAIL FROM: <[email protected]> =250 2.1.0 Sender OK > RCPT TO: <[email protected]> =250 2.1.5 Recipient OK
