SMTP Relay Map — Per-Domain Configuration

Not all domains route through Core's relay. Map of known SMTP relays.

IT Pro Partner / Sho'Nuff

• SMTP: mail.germainebrown.com:2525
• Backend: MXroute Exim (heracles.mxrouting.net)
• Auth: shonuff@germainebrown.com / shonuff.pass
• IMAP: mail.germainebrown.com:993 — Sent folder stores copies via IMAP APPEND

Apex Track Experience

• SMTP: c1113726.sgvps.net:2525
• Backend: SiteGround shared hosting
• Auth: contact@apextrackexperience.com / apex.track!!
• IMAP: c1113726.sgvps.net:993
• Note: This is SiteGround's SMTP, NOT Core's relay. The apex-mail-watchdog tests this relay specifically.

Pitfall: Wrong Relay

When sending from contact@apextrackexperience.com, always use c1113726.sgvps.net:2525, NOT mail.germainebrown.com:2525. Using Core's relay with Apex credentials will fail — different SMTP server, different auth domain.
