SE_INVOICE_FREE_WEBMAIL_REMITTANCE
What it means
Invoice/payment document routes remittance contact through a consumer webmail domain.
Why it fires
Legitimate vendor invoices can include payment instructions, but a bank-transfer or remittance workflow that points to generic consumer webmail (for example gmail.com, outlook.com, mail.com, or post.com) is a strong business-email-compromise indicator, especially when the document impersonates a named organisation.
