Hello, I've been trying to solve this problem for the last two hours.
I have the toaster installed and a virtual domain set up. I added a mailbox to the domain using qmailadmin,which adds the mailbox without error. I can see the mailbox in several places when looking at the server config using Webmin. I can access the mailbox via POP using telnet 110 without error. But whenever I try to send mail to that new mailbox, no matter what I try, it's always being rejected with a "Sorry, no mailbox here by that name. (#5.1.1)" from qmail-send on the receiving server. (BTW, I get the same error if I try to send mail to a real non-existent email address). I'm not sure what else to try. A similar mailbox "postmaster" to the same domain works perfectly. I've tried deleting and re-creating this new mailbox several times several different ways, yet qmail still rejects mail to the mailbox. Are there any simple tests or places to check what could be causing this? I'm not an expert, but I have installed and used the toaster several times already, and have never seen this happen. Thanks, -Hank
