Postfix 通過 virtual_alias_maps 將外發電子郵件發回給我

我有一個 postfix 郵件伺服器設置為將所有電子郵件轉發到我的域，*@example.com，到單個虛擬郵箱：me@example.com.

我用這個配置做到了：

/etc/postfix/main.cf

virtual_alias_maps = mysql:/etc/postfix/mysql-virtual-alias-maps.cf regexp:/etc/postfix/aliases-regexp

/etc/postfix/aliases-regexp （應該轉發任何還沒有去的東西me@example.com）

!/me@example\.com/ me@example.com

接收郵件工作正常：

postfix/smtpd[5852]: connect from unknown[108.60.212.145]

postfix/qmgr[5787]: 64CB91090: removed

注意這一行：

postfix/pipe[5858]: E7D49E27: to=<me@example.com>, orig_to=<test@example.com>, relay=spamassassin, delay=0.54, delays=0.13/0.01/0/0.4, dsn=2.0.0, status=sent (delivered via spamassassin service)

表明該消息的目的test@example.com是發送給me@example.com. 這很好。不幸的是，它也發生在出路時。這會導致傳出消息被發回給我。

postfix/lmtp[5862]: BA93CE27: to=<me@example.com>, orig_to=<test@ismyemailworking.com>, 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 <me@example.com> QzBoOSXPiluGGAAASQqZ1w Saved)

這是發送郵件時的完整日誌：

postfix/trivial-rewrite[5856]: warning: do not list domain example.com in BOTH virtual_mailbox_domains and relay_domains
postfix/submission/smtpd[6260]: BA93CE27: client=mail-pl1-f178.google.com[209.85.214.178], sasl_method=PLAIN, sasl_username=me@example.com

postfix/qmgr[5787]: BA93CE27: removed

結果是我的消息似乎沒有發送，我什至沒有收到錯誤消息。

在 Postfix 中為域創建包羅萬象的選項有很多，您的選項相當複雜。通常的方法是擁有virtual_alias_maps = hash:/etc/postfix/virtualwith @example.com me。postmap /etc/postfix/virtual使用時請記住hash:。

我通過更改/etc/postfix/aliases-regexp為：

if /(.*)@example.com/
!/me@example\.com/ me@example.com
endif

if 語句首先檢查郵件是否發送到域，其中不包括外發郵件。
