Yeah, never ever use BOUNCE feature ! PopTray does all that and there is no useless bounce feature... plus, it's completely free, not like MailWasher. If you use freeware version, you are limited to one pop account only... not the case with PopTray. You can have as many accounts as you want, and also, you can configure PopTray to alarm you with specific sounds, unique for each account... maybe not so important, but for sure, very useful. I'm not 24/7 in front of my screen, so I always know when some e-mail arrives, and also what account is involved. Only one is for business purposes, one for newsgroups (keeps spammers away from my mailbox), and few for registering to some forums.
Cheers !
