我最近设置了一个 postfix(+dovecot)邮件服务器(在 VPS 上),当我在自己的家庭网络中(我将其放在 mynetworks 中)时,我既可以发送也可以接收邮件。
但是当我不在家时,我只能接收电子邮件,这不是我期望的行为,因为那时我可能需要发送电子邮件。以下是我的设置,如果您能帮助我:
# See /usr/share/postfix/main.cf.dist for a commented, more complete version
# Debian specific: Specifying a file name will cause the first
# line of that file to be used as the name. The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no
# appending .domain is the MUA's job.
append_dot_mydomain = no
# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h
readme_directory = no
# See http://www.postfix.org/COMPATIBILITY_README.html -- default to 2 on
# fresh installs.
compatibility_level = 2
#Mail filter
#milter_default_action = accept
#milter_protocol = 6
#smtpd_milters = unix:/var/run/clamav/clamav-milter
#non_smtpd_milters = unix:/var/run/clamav/clamav-milter
# TLS parameters
smtpd_tls_cert_file=/etc/letsencrypt/live/mail.myserver.dev/fullchain.pem
smtpd_tls_key_file=/etc/letsencrypt/live/mail.myserver.dev/privkey.pem
smtpd_tls_security_level=encrypt
smtpd_use_tls = yes
smtpd_tls_auth_only = yes

smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
smtpd_relay_restrictions = permit_sasl_authenticated, reject_unauth_destination
smtpd_recipient_restrictions =
permit_mynetworks,
permit_sasl_authenticated,
reject_unauth_destination
mydomain = myserver.dev
myhostname = $mydomain
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = localhost.localdomain localhost
relayhost =

smtp_sasl_security_options = noanonymous
smtp_sasl_tls_security_options = noanonymous
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
smtpd_sasl_tls_security_options = noanonymous
smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth
smtpd_client_connection_count_limit = 10
smtpd_client_connection_rate_limit = 30
smtpd_error_sleep_time = 1s
smtpd_soft_error_limit = 10
smtpd_hard_error_limit = 20
这里还有 master.cf
smtp inet n - y - - smtpd
#smtp inet n - y - 1 postscreen
#smtpd pass - - y - - smtpd
#dnsblog unix - - y - 0 dnsblog
#tlsproxy unix - - y - 0 tlsproxy
submission inet n - n - - smtpd
-o smtpd_tls_security_level=encrypt
-o smtpd_sasl_auth_enable=yes
-o smtpd_sasl_type=dovecot
-o smtpd_sasl_path=private/auth
-o smtpd_sasl_security_options=noanonymous
-o smtpd_sasl_local_domain=$myhostname
-o smtpd_client_restrictions=permit_sasl_authenticated,reject
-o smtpd_sender_login_maps=hash:/etc/postfix/virtual
-o smtpd_sender_restrictions=reject_sender_login_mismatch
-o smtpd_recipient_restrictions=reject_non_fqdn_recipient,reject_unknown_recipient_domain,permit_sasl_authenticated,reject
#submission inet n - y - - smtpd
我不知道我更改了什么设置,但现在我得到了不同的错误。我之前得到的第一个错误是:
May 26 11:57:36 vmi1240278 postfix/smtpd[1164363]: connect from unknown[XX.XXX.XX.XX]
May 26 11:57:37 vmi1240278 postfix/smtpd[1164363]: NOQUEUE: reject: RCPT from unknown[XX.XXX.XX.XX]: 554 5.7.1 <[email protected]>: Relay access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<smtpclient.apple>
May 26 11:57:37 vmi1240278 postfix/smtpd[1164363]: disconnect from unknown[XX.XXX.XX.XX] ehlo=2 starttls=1 mail=1 rcpt=0/1 quit=1 commands=5/6
现在我得到:
May 26 16:28:33 vmi1240278 postfix/smtpd[1177893]: connect from unknown[XX.XXX.XX.XX]
May 26 16:28:33 vmi1240278 postfix/smtpd[1177893]: NOQUEUE: reject: RCPT from unknown[XX.XXX.XX.XX]: 554 5.7.1 <unknown[XX.XXX.XX.XX]>: Client host rejected: Access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<smtpclient.apple>
May 26 16:28:33 vmi1240278 postfix/smtpd[1177893]: disconnect from unknown[XX.XXX.XX.XX] ehlo=2 starttls=1 mail=1 rcpt=0/1 quit=1 commands=5/6
可能有用的其他信息是,当我在邮件应用程序中使用连接检查器时,我获得 SMTP(翻译):已连接,无需进行身份验证,而对于 IMAP,我获得(翻译):已连接并已验证
对于 Gmail,我获得的结果与我的服务器的 IMAP 的 SMTP 和 IMAP 相同。
谢谢。
答案1
好吧,这可能听起来很蠢。
该问题与 Apple Mail 自动管理 SMTP 连接有关,我取消选中它并将身份验证选项从“无”改为“密码”。已修复。
