Mail not being processed?

[lapos...@gmail.com]

Hi,

I'm setting up a high performance mailserver using multi-instance postfix with TLS and opendkim. This machine is only for sending.

In the maillog I usually see a message getting injected, cleaned, then DKIM is added, it's added to the queue, delivered and removed.

However, often I only see the DKIM line for a specific id:

May 24 14:33:04 bartok opendkim[1637]: D82B610AD: DKIM-Signature field added (s=k1, d=bounced.nl)

With no mention of D82B610AD elsewhere in the logs. Does this mean the mail is not processed by postfix?

Thanks in advance.

To answer my own question: this wasn't an issue with postfix or opendkim, but with log messages being suppressed by systemd-journal. Editing the ratelimits in /etc/systemd/journald.conf solved it.
