## Description
When an inbox name or business name contains parentheses — e.g. `Giro
Crédito - Soporte (Email` — the resulting From header becomes
unparseable by SMTP servers. The `(` is interpreted as an RFC 5322
comment start, swallowing the actual email address and causing a `553
Invalid email address` rejection.
