Email to SMS texing failing
We send text using email thru SendGrid. Most of the emails are bounced back after many deferrals to SendGrid when trying to be delivered to tmomail.net with the following bounce backback errors: 421 tmo-ibgw-5002a.ext.cloudfilter.net cmsmtp 149.72.130.204 blocked AUP#CNCT 452 4.1.0 <bounces+14645690-9958-+17072081891=tmomail.net@prod.ehi.com> server temporarily unavailable AUP#MXRT 421 tmo-ibgw-5003a.ext.cloudfilter.net cmsmtp too many sessions from 149.72.130.204 AUP#CNCT Is there something I need to tell T-Mobile or have Cloudfilter.net fix? We really don't see this issue when sending emails to other carriers such as Verizon. Thanks EricSolved503Visto0likes1Comentario
