Carol, On FreeBSD 3.1-Release, where the system is able to handle up to 16 characters for the username, is qpopper able to use larger than 8 without the pop virtuser patch mentioned below? I actually intend to use the virtusertable for this system. AIMS has so many problems with it, and no real support for virtual hosts. Which brings me to a new question, if I may be so bold. I have only setup sendmail on my second favorite OS, Solaris. Is the 'hash' method any different than the 'dbm' format that I'm used to setting up on Solaris? If so, are there any suggestions or warnings before I dive in?
