‎554 5.7.1 Rejected by ESETS_SMFI (spam)‎


Recommended Posts

Dobrý deň,

Chcel by som Vás požiadať o pomoc s non-delivered mailami, ktoré sa vracajú zatiaľ z dvoch identifikovaných domén (concept.sk, domodea.sk).
Maily sú posielané zo služy M365 Exchange Online.

Error: ‎554 5.7.1 Rejected by ESETS_SMFI (spam)‎

Error Details:
Reported error: 550 5.7.350 Remote server returned message detected as spam -> 554 5.7.1 Rejected by ESETS_SMFI (spam)
DSN generated by: AM9PR08MB6209.eurprd08.prod.outlook.com

Výsledok z https://www.mail-tester.com 8.2/10, "Good stuff. Your email is almost perfect"

Viete prosím preveriť, či sa niektorá z IP služby O/M365 EXO nedostala na blacklist, prípadne ako postupovať pri komunikácii/trloubleshootingu so správcami dotknutých domén?

Tuto verím že sú rozsahy ktoré používa služba O/M365 EXO: Office 365 URLs and IP address ranges - Microsoft 365 Enterprise | Microsoft Docs
