#268 OpenDKIM slows to a crawl outgoing mails at Postfix
Dear All!
OpenDKIM signs mails and it takes too much time.
Example (50 MB mail size):
Without OpenDKIM: transmission time is around 5 sec.
With OpenDKIM: transmission time is around 120 sec.
I was looking at Postfix logs and the issue was by the OpenDKIM.
So, I've disabled the service and mails flow works like a charm.
CPU usage ca. 1%.
OS: FreeBSD 11.1p4 (bhyve)
Service: opendkim-2.10.3_7
Mail: postfix-3.2.3_1,1
opendkim.conf
LogWhy yes
Syslog yes
SyslogSuccess yes
NameServers 8.8.8.8, 8.8.4.4
Canonicalization relaxed/simple
KeyTable /usr/local/etc/mail/KeyTable
SigningTable /usr/local/etc/mail/SigningTable
SignatureAlgorithm rsa-sha256
Socket inet:8891@localhost
DNSConnect yes
DNSTimeout 5
ReportAddress root
SendReports yes
TemporaryDirectory /var/db/opendkim/tmp
main.cf
smtpd_milters = inet:127.0.0.1:8891, inet:127.0.0.1:8893
non_smtpd_milters = $smtpd_milters
milter_default_action = accept
Thanks for any help.
Kind Regards,
