antivir-milter changed licencing

[David A. Koran]

I'm not sure how many of you folks noticed, but it looks like H+BEDV 
Datentechnik GmbH has changed their licensing restrictions on the virus 
DAT updates and as of Friday evening, this version within FreeBSD no 
longer works with the "private" (aka FREE) license for the product. 
Please consider mentioning this as a build option or speak with the 
appropriate folks about the licensing terms.

Sincerely,

David A. Koran
