Refer to the exhibits, showing SMTP limits (Session Profile -- SMTP Limits), and domain settings (Domain Settings, and Domain Settings -- Other) of a FortiMail device. Which message size limit in KB…

Question

Exhibits

Options

• A204300
• BThere is no message size limit for outbound email from a protected domain.
• C10240
• D51200

• A
  6% (1)
• B
  25% (4)
• C
  6% (1)
• D
  63% (10)

Explanation

Option D (51200 KB) is correct because FortiMail applies the domain-level message size limit from Domain Settings for outbound email originating from a protected domain - domain-specific settings take precedence over the Session Profile SMTP Limits for traffic associated with a configured protected domain.

Why the distractors are wrong:

• A (204300 KB) is likely a different limit shown in the exhibits (e.g., a session-level byte cap or unrelated field) - it does not represent the applicable outbound message size limit for the protected domain.
• B is wrong because FortiMail absolutely enforces message size limits on outbound email; no protected domain bypasses size enforcement by default.
• C (10240 KB) is the Session Profile SMTP limit, which is the trap answer - this applies to sessions not governed by domain-specific settings, but the protected domain's own Domain Settings override it for outbound traffic.

Memory tip: Think "Domain Dominates" - when a message flows from a protected domain, the Domain Settings win over the Session Profile. In the exhibit hierarchy, always look at Domain Settings first for protected-domain traffic, and use the Session Profile limit only as a fallback for unprotected/relay sessions.
