Function: systemSenderAddress()
systemSenderAddress(
source):string|undefined
The address SYSTEM mail sends from, or undefined when nothing configured
yields one: an explicit ResolvedSender.systemFrom wins, else
no-reply@<domain>, else the fixed from.
no-reply@<domain> outranks a configured from on purpose. A fixed from is
typically a person or a team address chosen for mail a HUMAN sent, and a
verification code arriving from it invites a reply nobody reads. Set
systemFrom / EMAIL_SYSTEM_FROM to name the address explicitly (a monitored
support@, a differently-spelled donotreply@).
Returns undefined rather than throwing so config resolution can fold the result into the sender allow-list before any send happens.
