Hello, My name is Tim and I work for a regional ISP, Amplex (www.amplex.net) and have over the last few weeks received multiple reports of automated style messages bouncing/being deferred endlessly to [email address removed per the Verizon Terms of Service] which previously worked. Upon testing this is effecting our internal ticketing system also which is receiving the same defferred message and effecting all of our automated notification systems customers use. This appears to be effecting multiple systems and multiple message types. I'm happy to escalate this to an engineer and can be contacted at [email address removed per the Verizon Terms of Service]. I can provide the non-redacted "to" fields so VZW can locate these messages as needed. Example deferred messages: Internal server (nms0) Nov 14 09:25:09 nms0 postfix/smtp[26540]: F1BFA138076D: to=<[email address removed per the Verizon Terms of Service]>, relay=smtpin02-mms.vzw.a.cloudfilter.net[3 5.160.118.79]:25, delay=59189, delays=59189/0.01/0.39/0, dsn=4.0.0, status=deferred (host smtpin02-mms.vzw.a.cloudfilter.net[3 5.160.118.79] refused to talk to me: 554 vzw-ibgw-6003a.stratus.cloudmark.com cmsmtp ESMTP server not available - POL103 - VG3 ZiHWHWHWhQ) Baracuda E-mail security gateway (cuda.amplex.net) 2019-11-14 09:24:45 host smtpin02-mms.vzw.a.cloudfilter.net[35.160.118.79] refused to talk to me: 554 vzw-ibgw-6003a.stratus.cloudmark.com cmsmtp ESMTP server not available - POL103 - VG3BiHW3aHWhQ 2019-11-14 06:14:45 host smtpin02-mms.vzw.a.cloudfilter.net[35.160.118.79] refused to talk to me: 554 vzw-ibgw-6003a.stratus.cloudmark.com cmsmtp ESMTP server not available - POL103 - VD5JiFnEkHWhQ
