我的postfix郵件伺服器下的一個郵件域xx.com能發不能收。求解答。付上配置。在線等

郵件伺服器下有三個郵件域。別的都正常。只有xx1.com不行。能發,但不能收。而且最近幾天都收到很多退信。難道是被人搞了退信攻擊和被垃圾郵件伺服器拉入黑名單了?
這是main.cf配置
# cat main.cf
mynetworks = 127.0.0.1
myhostname = mail.xx.com
mydestination = $mynetworks $myhostname
maximal_queue_lifetime = 3d
bounce_queue_lifetime = 1d
message_size_limit = 20240000
queue_minfree = 200000000
mail_name = Postfix - by extmail.org
smtpd_banner = $myhostname ESMTP $mail_name
smtpd_error_sleep_time = 0s
unknown_local_recipient_reject_code = 450
virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf
virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf
virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf
virtual_transport = maildrop:
maildrop_destination_recipient_limit = 1
command_directory = /usr/sbin
config_directory = /etc/postfix
daemon_directory = /usr/libexec/postfix
data_directory = /var/lib/postfix
debug_peer_level = 2
html_directory = no
mail_owner = postfix
mailq_path = /usr/bin/mailq
manpage_directory = /usr/local/man
newaliases_path = /usr/bin/newaliases
queue_directory = /var/spool/postfix
readme_directory = no
sample_directory = /etc/postfix
sendmail_path = /usr/sbin/sendmail
setgid_group = postdrop
unknown_local_recipient_reject_code = 550
smtpd_recipient_restrictions =
    permit_mynetworks,
    permit_sasl_authenticated,
    reject_non_fqdn_hostname,
    reject_non_fqdn_sender,
    reject_non_fqdn_recipient,
    reject_unauth_destination,
    reject_unauth_pipelining,
    reject_invalid_hostname,
broken_sasl_auth_clients = yes
smtpd_sasl_auth_enable = yes
smtpd_sasl_local_domain = $myhostname
smtpd_sasl_security_options = noanonymous
smtp_helo_name = mail.xx.com

《解決方案》

dns有沒有問題呢
《解決方案》

問題可分為兩部分看待:

一  能發不能收,這個問題你查下該域是否做了MX記錄,這個狀況最明顯的原因就是這個問題。

二  收到很多退信,這個需要分析具體是收到誰的退信,是那些賬號收到退信,你說的問題有點太模糊了。說清楚了,才能分析。
《解決方案》

我只能說你提供的maillog沒有有用信息
