There are a few possibilities.

She is posting from a domain with a DMARC policy of reject or quarantine
and the list's dmarc_moderation_action is Discard.

You have configured a list of tuples of the form (header, regexp) in
KNOWN_SPAMMERS in mm_cfg.py and some header in her message matches a
corresponding KNOWN_SPAMMERS regexp.

You have configured header_filter_rules and a rule with action Discard
matches this message.

None of these honor the forward_auto_discards setting.
