ALERT: Profane message stopped

I got this when trying to send an email to a good friend of mine at her work email. The funny thing is, is that the profane word (sh*t) was in her original email to me (which got through) and therefore, was included when I hit reply. So, the bank's policy deems it unacceptable to receive profane words, but not send them. Pretty funny.

The IT department has automatically stopped an email sent by you to my.friend@her-company.com because it contained profanity. The use of profane language contravenes the company’s email Acceptable Usage Policy.
