Re: Email from mainframe host to my cell phone rejected
tmkruse68 Did you ever get an answer to your issue. Our company sends email to text to our employees thru SendGrid and we are getting the same bounce back for our tmobile users. 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#CNCT39Views0likes0CommentsRe: Email to SMS
I would also like to know the answer. We are experiencing many blocks due to timeouts and too many connection issues and wondering if we are already being throttled? 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#CNCT48Views0likes0CommentsEmail 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 EricSolved426Views0likes1Comment
