我係用hkbn   用debian set左部server
但係因為唔見左之前個設定檔,依家部機可寄不可收
上網睇左好多教學,但改黎改去都係唔得

有冇人可以幫下手

我同你掉轉,研究緊under1的那台Linux,而家係可收不可寄!

i553041@msn.com... Deferred: Connection timed out with mx3.hotmail.com.
Warning: message still undelivered after 4 hours
Will keep trying until message is 5 days old

個SMTP SSL可用,用ThunderBird寄到野,但無耐之後就打回頭!

收就收到:
[root@localhost sbin]# mail
Mail version 8.1 6/6/93.  Type ? for help.
"/var/spool/mail/i553041": 1 message 1 unread

請問咩係External Mail Server?

姐係用hkbn個smtp....因為佢block左25

hmmm...我無咁諗過...我想真真正正起個SMTP,用SMTP SSL
但...睇返log...個個都係咁:

應該唔關台自己個SMTP Server事吧?看個log好像各大Free E-mail供應商都將台Mail Server的IP block了!(可能是將香港寛頻的IP block了!)

言歸正傳...你個DNS會唔會係未SET MX record?

好似係hkbn block晒....

我set左....之前我試過一次work...就係重安server果陣唔見得backup個config檔,依家整唔返

如果你話收唔到信,應該係關呢一part設定事...但我又唔覺個設定有咩問題喎!

# Receiving messages parameters
mydestination                = localhost, localhost.localdomain, $myhostname, $mydomain
append_dot_mydomain          = no
append_at_myorigin           = yes
local_transport              = local
virtual_transport            = virtual
transport_maps               = hash:/etc/postfix/ispcp/transport
alias_maps                   = hash:/etc/aliases
alias_database               = hash:/etc/aliases

有無check過System個Maillog?
有無咩error message呀?

試左3日終於得左....
原來係mydomain果一度要唔可以重覆
同埋下面有一個check_policy_service唔記得disable佢
