The present setup for HamiMail (and AtMail if you’re an AtomIC user) will NOT forward your e-mails to your private address at the moment. The software has a problem which means that its not properly detecting loops, so if you’ve misconfigured your account to forward to private address but had your private address set to firstname.lastname@example.org (which isn’t a good idea anyway, for many reasons!) it would create a loop whereby the message would always be trying to be sent between Hamimail and the internet.
I do intend to fix it to restore normal service, but in the meantime please login to the web mail client to read any deardiary.net e-mail. You’ll hopefully be pleasantly surprised by how little spam there is in there now anyway 🙂 The address is of course www.hamimail.com, unless you’re an AtomIC user in which case you need atmail.atomic-systems.com
