以下是客戶寄過來我們檔信的錯誤訊息:
May 16 11:05:38 mailsvr postfix/smtpd[16409]: NOQUEUE: reject: RCPT from unknown[60.251.214.207]: 450 4.7.1 <bmcmse.benqmaterials.com>: Helo command rejected: Host not found; from=<Michelle.Chen@Sigma-medical.com.tw> to=<ben_lin@xxx.xxx> proto=ESMTP helo=<bmcmse.benqmaterials.com>
我有發現到是main.cf 底下
smtpd_helo_restrictions =
permit_mynetworks
permit_sasl_authenticated
check_helo_access pcre:/etc/postfix/helo_access.pcre
reject_non_fqdn_helo_hostname <--- 這個註解掉就可以送達了
reject_unknown_helo_hostname <----這個註解掉就可以送達了
請問reject_non_fqdn_helo_hostname ,reject_unknown_helo_hostname 這2個註解掉 這會攸關安全性問題嗎?
還是我能怎ㄇ處理??
