On-prem SMTP Relay server slow
Hi, i have 2 on-prem SMTP Relay server in windows 2016; the flow is application > SMTP Relay > DLP Server > Recipient; but starting from last Thursday, i notice all the email always got delay for 2 hours stuck at SMTP relaye server which i can't figure out why. Everything is good and intact from OS layer, any advice?
Both server KB, build, lastreboot, able to tlenet at port 25, able to lookup/ping DLP server, etc all same. Thanks
