Description

Summary

Almwerk Foods' mail server deferred our notices from 08.10 to 11.15: too many messages to addresses that no longer exist there. Mailcrest retried and everything arrived by 11.20.

Cause

We keep mailing addresses that hard-bounce. Almwerk removed 30 leavers in March; we mailed them daily.

Follow-ups

Stop mailing hard-bouncing addresses: ENG-1387.
