Check the Qmail control files (rcpthosts, virtualdomains), as well the "assign" file in the users/ subdirectory of your Qmail directory. Specifically, look for the domain in question, and make sure it is there.
Hi list: It's been now almost a yearbash-2.05# uptime 3:56pm up 345 days, 4:13, 3 users, load average: 0.00, 0.00, 0.00 since our mail server started. Everything has been OK until now. Suddenly, the users of one of the virtual domains are now facing a problem. They cannot receive messages, the mail server rejects all the incoming messages with the following note: Hi. This is the qmail-send program at mail.<ourdomain>.com. I'm afraid I wasn't able to deliver your message to the following addresses. This is a permanent error; I've given up. Sorry it didn't work out. <[EMAIL PROTECTED]>: Sorry, no mailbox here by that name. (#5.1.1) I tried to solve this by looking in the available information, but what I found so far, are problems related to the NIS service, or nothing similar to our problem. The configuration has not been changed at all. The only difference here is the increasing number of users (We have 1225 now) and the fact that We are using ezmlm for mailling lists processing. Any help would be highly appreciated. Hugo Escobar System Administrator TravelOne International LLC
