我正在运行 dkimproxy 来签名和验证邮件。
我接收邮件时总是收到此错误。多年来我从未修复过它，但现在我想摆脱它
Dec 11 13:44:54 cole dkimproxy.in[1193]: DKIM verify - invalid (public key: DNS query timeout for me._domainkey.booking.com at /usr/lib/perl5/vendor_perl/5.18.1/Mail/DKIM/DNS.pm line 156, <_GEN_1> line 492.); message-id=<[....]@memta-103.ams4.prod.booking.com>, signer=<@booking.com>, sender=<[email protected]>
这与每个发送者都一致。这看起来不像是网络问题，因为以下命令可以由 root 运行（以dkim用户身份运行）
cole:/etc/postfix # sudo -u dkim dig -t txt me._domainkey.booking.com

Sommario: DKIMproxy is an SMTP-proxy that implements the DKIM and DomainKeys standards
Descrizione:
DKIMproxy is an SMTP-proxy that signs and/or verifies emails, using the
Mail::DKIM module. It is designed for Postfix, but should work with any
mail server. It comprises two separate proxies, an "outbound" proxy for
signing outgoing email, and an "inbound" proxy for verifying signatures
of incoming email. With Postfix, the proxies can operate as either
Before-Queue or After-Queue content filters.
