# SMTP Recipient Pitfalls

**Last updated:** Jul 10, 2026

## Valid Recipient Address — Critical

The ONLY valid recipient for Germaine is `g@germainebrown.com`.

- `g@germainebrown.com` — ✅ 250 Accepted by MXroute
- `germaine@germainebrown.com` — ❌ 550 No such recipient here
- `g@iamgmb.com` — ❌ 550 No such recipient here
- `germaine@itpropartner.com` — ❌ 550 No such recipient here

The MXroute Exim server at `mail.germainebrown.com:2525` rejects any address that doesn't have a mailbox on the server. Only `shonuff@germainebrown.com` (sender) and `g@germainebrown.com` (recipient) have mailboxes.

**Always BCC shonuff@germainebrown.com** on every outbound send — partially as a record, partially so the shonuff-inbox-collect.py can detect replies.
