That was my impression, too. (I only saw it by sheer accident, rotated log files are mailed to me, but i only RET over them, yet it was in the visible space.) And no, they all went through five minutes after. In fact yet another two mails were sent out a few minutes ago, and these went through directly again. But impressive that you all see such things. Maybe i should only filter better and sent postmaster@ such delivery problems? Hm. Regarding DKIM, SPF, ARC and DMARC: i am impressed how the engineers of the world address the problem of overly excessive resource usage. Anyhow it seems i am now forced to do at least DKIM, and let the SPF record remain even with ~all instead of -all. I hate it. --steffen | |Der Kragenbaer, The moon bear, |der holt sich munter he cheerfully and one by one |einen nach dem anderen runter wa.ks himself off |(By Robert Gernhardt) _______________________________________________ Postfix-users mailing list -- [email protected] To unsubscribe send an email to [email protected]
