That sounds very much like NDR spam where a spammer has spoofed an email (or several) that claim to come from her account and the recipient of the spam is rejecting the messages and the bounce-back goes to the spoofed sender, which is your user.

If you publish an SPF record, that should help others to reject spoofed emails as spam and also install / configure some good Anti-Spam tools such as Vamsoft ORF Fusion (www.vamsoft.com) - that should solve the problem for you.
