為什麼 dovecot 不發送電子郵件？

我有問題，dovecot 沒有將電子郵件發送到我的收件箱（圓形立方體）。

您的本地傳遞配置錯誤。從一個簡單的 Postfix 配置開始，用於傳遞本地郵件。有一些教程，例如：

http://rimuhosting.com/support/settingupemail.jsp?mta=postfix

在您的情況下，您可以從簡單的 Postfix 配置開始，您的 dovecot 配置似乎沒問題。您可以從這個簡單的後綴配置開始。

main.cf

config_directory = /etc/postfix
mailbox_transport = dovecot
virtual_alias_domains = /etc/postfix/virtual-domains
virtual_alias_maps = hash:/etc/postfix/virtual
myhostname = lars-dev.de
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = localhost
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
message_size_limit = 0
mailbox_size_limit = 0
virtual_mailbox_limit = 0
recipient_delimiter = +
inet_interfaces = all
smtpd_banner = postfix mailserver

smtpd_recipient_restrictions =
                               permit_mynetworks,
                               permit_sasl_authenticated,
                               reject_unauth_destination                                   

/etc/postfix/虛擬域

lars-dev.de

/etc/postfix/虛擬

web@lars-dev.de  web
userxy@lars-dev.de userxy

執行 postmap /etc/postfix/virtual 並重新啟動 postfix，這個簡單的配置應該適合你。如果這可行，您可以通過 mysql 為虛擬使用者添加一些東西
