I am a newbie and don't have a clue where to start. Do I need to setup a DNS serve
it, I've found another software package that seems to have difficulty with the sendmail 8.6 two-line greeting (we all knew abotu Soft*Switch already, right?). This time it's "The Major BBS" software. I don't know which particular versions may have this problem and whether a later version fixes it, or whether it's configurable or not, but at least some versions definitely have this problem. Just thought you might want to know. -- Mail Systems Administrator Ph: (703) 918-2256 for http://www.linuxquestions.org/questions/linux-networking-3/email-server-setup-imap-smtp-96198/ America Online, Inc.

ISC + Sendmail 8.6.9: error on output channel sending "220 ESMTP spoken here" I run a ISC unix box with sendmail 8.6.9, and it works just fine, but there's a few mail relays that give me some trouble, as I get from those relays (and only those) lots http://www.verycomputer.com/4_60383bdda95a4f22_1.htm of:
good, bad or incomplete: Range Purpose 1xx Positive Preliminary reply The requested action is being initiated; expect another reply before proceeding with a new command. (The user-process sending another command https://en.wikipedia.org/wiki/List_of_FTP_server_return_codes before the completion reply would be in violation of protocol; but server-FTP processes should queue any commands that arrive while a preceding command is in progress.) This type of reply can be used to indicate that the command was accepted and the user-process may now pay attention to the data connections, for implementations where simultaneous monitoring is difficult. The server-FTP process may send at most, one 1xx error on reply per command. 2xx Positive Completion reply The requested action has been successfully completed. A new request may be initiated. 3xx Positive Intermediate reply The command has been accepted, but the requested action is being held in abeyance, pending receipt of further information. The user should send another command specifying this information. This reply is used in command sequence groups. 4xx Transient Negative Completion reply The command error on output was not accepted and the requested action did not take place, but the error condition is temporary and the action may be requested again. The user should return to the beginning of the command sequence, if any. It is difficult to assign a meaning to "transient", particularly when two distinct sites (Server- and User-processes) have to agree on the interpretation. Each reply in the 4xx category might have a slightly different time value, but the intent is that the user-process is encouraged to try again. A rule of thumb in determining if a reply fits into the 4xx or the 5xx (Permanent Negative) category is that replies are 4xx if the commands can be repeated without any change in command form or in properties of the User or Server (e.g., the command is spelled the same with the same arguments used; the user does not change his file access or user name; the server does not put up a new implementation.) 5xx Permanent Negative Completion reply The command was not accepted and the requested action did not take place. The User-process is discouraged from repeating the exact request (in the same sequence). Even some "permanent" error conditions can be co
