#928 Delayed Delivery after SM or CSI should come from account
Some? CSI modules as well as the SM module add a delayed delivery where from=domain. However that gets us into trouble for reasons described on the mailing list.
If the delayed delivery would come from the accounts bare jid we could avoid a lot of those problems while facing no downsides (That I can see).
The XEP currently doesn't say anything in this regard. (It doesn't mention delayed delivery at all). But I'm in the process of adding this.
