In that case, it’s likely a bit of the content of the email that’s triggering some of their internal filters. MS has, for a long time, had a policy of dropping mail in the floor if they judge it to be bad enough after they’ve accepted it. If it’s particular messages then there’s a content (links, URLs, landing pages) issue somewhere.
If it’s only to one address then it’s possible that address has some filter that’s causing the mail to drop. I know I investigated something a while back where if customers created “never send me email with <word> in it” the mail wouldn’t be delivered. laura > On Nov 22, 2017, at 7:39 AM, David Hofstee <opentext.dhofs...@gmail.com> > wrote: > > Hi Klaus, > > No, actually it was perfectly repeatable.
