If mysql is in USE, this patch should be included in sys-apps/ucspi-tcp: http://matt.simerson.net/computing/mail/ucspi-tcp-0.88-mysql.patch It will help alot when useing vpopmail with mysql and roaming users. The ebuild change should be trivial but I'm not sure on howto add new files into the existing ebuild, sorry.
sorry, no time :(
This is a very unclean solution to the roaming users problem. The patch is totally undocumented, and I see several possible security issues with the code it adds. I'll only apply this if the security ramifications get looked at the some better documentation written. I strongly suggest you look up net-mail/relay-ctrl instead for the vpopmail roaming users problem. It actually becomes totally oblivious of you actually using vpopmail. Whether or not you use vpopmail doesn't matter, it will work perfectly in both cases.
