Hallo Zusammen,

 

ich habe momentan das Problem bei einem Exchange 2016 Server CU17 mit Spamfighter, dass Mails teilweise Stark verzögert oder gar nicht zugestellt werden. Ich habe das Zertifikat geprüft und nochmal an SMTP gebunden, IIS Crypto Best practise. Bin mir nun nicht sicher wo ich noch so suchen kann.

 

Gerade nochmal DNS geprüft und aufgeräumt. Noch jemand eine Idee?
