1. Not likely, but not impossible... To Quote a source The /dev/random device hands out "high-quality" random bits, up to the limit of the "random" information it has been seeded with. The /dev/urandom device does not have this limitation. It continues to hand out bits of decreasing quality as lon

Hello all, I'm new to Cyrus. Historically, I've used Qpopper, Sendmail, and UW IMAP. We recently switched to Cyrus for IMAP. It came highly recommended... We've got this on a darned burly machine, running some very recent version of Debian, with a fast CPU, 4GB RAM, and fast SAS drives. When
