我設定了一個 postfix 郵件伺服器，將所有電子郵件轉發到我的網域 ，*@example.com到單一虛擬郵箱：[email protected]。
我用這個配置做到了這一點：
/etc/postfix/main.cf
virtual_alias_maps = mysql:/etc/postfix/mysql-virtual-alias-maps.cf regexp:/etc/postfix/aliases-regexp
/etc/postfix/aliases-regexp
（應該轉發任何東西不是已經要去[email protected]）
!/me@example\.com/ [email protected]
接收郵件工作正常：

注意這一行：
postfix/pipe[5858]: E7D49E27: to=<[email protected]>, orig_to=<[email protected]>, relay=spamassassin, delay=0.54, delays=0.13/0.01/0/0.4, dsn=2.0.0, status=sent (delivered via spamassassin service)
顯示該訊息的目的是發送至 ，[email protected]但已發送至[email protected]。這很好。不幸的是，這種情況也發生在出去的路上。這會導致外發訊息被傳回給我。
postfix/lmtp[5862]: BA93CE27: to=<[email protected]>, orig_to=<[email protected]>, relay=fqdn.example.com[private/dovecot-lmtp], delay=0.22, delays=0.19/0/0.02/0.02, dsn=2.0.0, status=sent (250 2.0.0 <[email protected]> QzBoOSXPiluGGAAASQqZ1w Saved)
這是發送郵件時的完整日誌：

postfix/qmgr[5787]: BA93CE27: removed
結果是我的消息似乎沒有發送，甚至沒有收到錯誤訊息。
答案1
在 Postfix 中建立網域的包羅萬象的選項有很多，但您的選項相當複雜。通常的方法是virtual_alias_maps = hash:/etc/postfix/virtualwith @example.com me。postmap /etc/postfix/virtual使用時切記hash:。
答案2
我透過更改/etc/postfix/aliases-regexp為解決了這個問題：
if /(.*)@example.com/
!/me@example\.com/ [email protected]
endif
if 語句首先檢查郵件是否要傳送到該網域，其中不包括外發郵件。
