Trying to implement dmarc and looking at configuration file Wondering if one should change reject failures to true and how can I get this before I start rejecting emails AuthservID mail.example.com PidFile /var/run/opendmarc.pid #Debian default RejectFailures false Syslog true TrustedAuthservIDs mail.example.com,mail2.example.com UMask 0002 UserID opendmarc:opendmarc IgnoreHosts /etc/opendmarc/ignore.hosts HistoryFile /var/run/opendmarc/opendmarc.dat #for testing: SoftwareHeader true Sent from my iPad -------------- n...

...C checking without using exceptions for the lists they are on. It's a known fact that DMARC does not cope well with mailing lists. Blindly enabling DMARC checks without thinking about the consequences for themselves should not be the problem of other well behaving participants. Most people use OpenDMARC and there are patches to mark certain hosts as mailing lists senders, so it is possible. And everyone using p=reject should think about it as well - as I said, DMARC does not play well with mailing lists, so setting p=reject on a domain used to participate on mailing lists is not wise, to say the...

...in /etc/sysconfig/saslauthd, which is now /run/saslauthd (rather than /var/run/saslauthd). And, of course, I use systemctl rather than chkconfig to control boot-time behavior. The trickier bit for me was stopping and restarting the whole SMTP toolchain, which includes spamassassin, clavav, and opendmarc. Below my .sig, I've included the shell script I use for that. -- Paul Heinlein <> heinlein at madboa.com <> http://www.madboa.com/ #!/bin/sh # # start/stop SMTP tool chain on mail.madboa.com # ====================================================================== LANG=C PATH=...

Just reading up on DMARC, toying with setting it up to auth against incoming emails. (but not configure my domain to use dmarc, or at least not yet) ran into an article about opendmarc, which is available on epel. but when I took a look at the opendmarc website and the git pages it doesn't appear to have been updated in several years. while I see that it is still available from epel, I wonder if anyone knows the project status? Is it still active? are there any other viable...

Hello all, I've been googling my brains out since yesterday looking for up-to-date information on this matter, and have found information that is anywhere from 15 to 5 years old. I'd really like some information that much more up to date on the subject. Specifically configuring Sendmail SMTP authentication (_no smart host stuff_). I've got Sendmail 8.14 installed on a CentOS 7.3

...duce it with both versions. My setup is that dovecot submission proxies to Exim on port 10025. The first mail gets through without any issues, but the second email will not get send. I had this issue at first with Apple Mail (it just sends a QUIT and shows an error) and could reproduce it with the OpenDMARC report perl script. You can find a little Perl script attached to reproduce it. It seems to me that Dovecot sends an (unexpected or mixed up) second answer to the client. If I add a ?$smtp->getline();? (line 110) sending multiple emails works again. Another workaround is to disable CHUNKING in...

Andr?, are you quite sure you have it working? In this thread someone from Open-Xchange stated that no, Dovecot doesn?t have SMTPUTF8 support implemented, and the same response was given by another Dovecot developer last September (it ?is being considered? was the answer then, see https://dovecot.org/pipermail/dovecot/2018-September/112887.html). I am using LMTP to deliver mail to Dovecot from
