Hm well, there is a notion on such things with SMTP authentication, IR (immediate response) for example. The above however .. i have to look around to give an answer, i have not looked in these RFCs for a long time. My gut says the above is not right, especially with the repeated status. Normally server uses 334-TEXT but for the last line, which then would be "334 TEXT", _if_ splitting _this_ very response is allowed. But two times "334 TEXT" is definetely wrong.
Ok, but what I'm seeing comes from s-nail's verbose mode, not directly from the server, so perhaps it's s-nail leaving out the '-' ?
May i ask what software this is?
If I telnet to the (successful) server, it responds with Sendmail 8.14.7/8.14.7. The problem server says Sendmail 8.15.2. Stephen Isard
