TSS04 is an NDR for traffic shaping that indicates that mail originating
from the network has been severely deprioritized. It's usually an

I'd be happy to share a frosty cold beverage and some of my (un)fortunate
insight into the spammy side of list composition data analysis. There are

Nic,
Orange has a concurrent connection limit of 3, but some of their MTAs sit
behind a NAT and have multiple external IPs. We've had to set our
concurrent connections to 1, which has helped immensely. If that doesn't

This has existed for 10-15 years, but you don't see it often. AOL

IPv6, DNSSEC, or delivery to Gmail
For NDRs and DSNs to be truly useful to an ESP, we tend to break them down
into more buckets than two.
Hard bounce/invalid (do not retry, generally a 5xx)
Soft bounce (temporary and re
