I decided to stop using my own mail server and migrate my accounts to Google Apps. Fairly easy and now I get many features... Website, docs, mail (with good anti-spam/virus system, and gmail webmail interface), etc. The migration was quite easy as I configured Gmail to get email in my inbox via POP3s, so as the MX propagates, I get all my mails in the Gmail account, even if they reached my old server. I copied my sent items folder via IMAPs. I should have done that a long time ago... And I installed Gmail for BlackBerry, so I have my e-mails in a separate interface. Google Apps even manage the abuse@ and postmaster@ addresses!
