Hi, the problem was fixed in Monit 5.2.4, changelog excerpt: --8<-- * Randomize the mail message id to prevent duplicates in the case, that the same hostname is used on multiple hosts running monit and messages are generated in the same second in parallel. Thanks to Sergey B Kirpichev. --8<-- Best regards, MartinOn 18 Oct 2017, at 16:43, Eric Pailleau <address@hidden> wrote: Hi, yes I will do if I got confirmation this is a monit issue for monit guys. thanks.

If monit create this id , this need more entropy. 1508333561.0 1508333561.1 etc... in same second, at least. monit guys may know if this issue is solved in upper version or not, too. regards Le 18/10/2017 à 16:17, SZÉPE Viktor a écrit :message-id=<address@hidden>It seems to be a timestamp based ID which it not precise enough for your case.

Le 18/10/2017 à 15:46, Eric Pailleau a écrit :Hello, I encountered a monit alert mail issue. I use simple config : check file no_acks with path /path/to/no_acks.log if match ".*" then alert So that monit effetively send a mail at each entry in this log. So far so good. But since we changed mail architecture, we did not received all the mails, but, by investigating , only the first one of all in the same second (using monit.log timestamp reference) We could find that imapd/cyrus removed duplicate message ids and could add a special config entry disabling this option. Indeed we could see in postfix/smtpd that all the mails was relayed, but all in the same second add same ID : example : Oct 18 15:32:41 sv1 postfix/cleanup[31715]: 9AE25A87C51: message-id=<address@hidden> Oct 18 15:32:41 sv1 postfix/cleanup[31715]: A59FDA87C3D: message-id=<address@hidden> It is not clear to me if this is a monit or postfix issue. Is this mail id set by monit or postfix ? Thanks for sharing any thoughts on this.
