## Updates from SMTP2GO
### 2025-09-07 23:30 UTC: resolved
Between 21:30 UTC and 23:15 UTC on September 7, a server misconfiguration temporarily affected email delivery. A small number of emails were rejected with the error "550 From header sender domain not verified", or some bounced emails with a DMARC error (for domains with a DMARC policy of reject). The issue was resolved, and all services are fully operational. We apologize for any inconvenience this may have caused.
