Hallo Vili,

On Tue, 3 May 2005 14:21:24 +0200GMT (3-5-2005, 14:21 +0200, where I
live), you wrote:

TBS>>> SMTP server is ok, the recipient email is ok, I get back this message:
TBS>>> 500 invalid domain name

TBS> ??? What does it exactly mean? This address I am sending from is
TBS> valid.

Here are the smtp reply codes:

RFC 821                                                      August 1982
                                           Simple Mail Transfer Protocol

      4.2.1.  REPLY CODES BY FUNCTION GROUPS

         500 Syntax error, command unrecognized
            [This may include errors such as command line too long]
         501 Syntax error in parameters or arguments
         502 Command not implemented
         503 Bad sequence of commands
         504 Command parameter not implemented

You're getting a 500, that's a syntax error, appended with the
remark 'invalid domain name', so my guess is that you're forgetting
something or you've got a dot in the name without quote marks around
it. Something like this: R.Otten <[EMAIL PROTECTED]> is incorrect while
this: "R.Otten" <[EMAIL PROTECTED]> is okay, something like that could
cause such a reply as you got. When you really want an intelligent
answer from this list, you've got to come with more data, like the
exact From: header (and completenesss' sake an exact From: header too)
and the smtp-server you're using.

Just to be complete, here are the rest of the reply codes from rfc821.
         
         211 System status, or system help reply
         214 Help message
            [Information on how to use the receiver or the meaning of a
            particular non-standard command; this reply is useful only
            to the human user]
          
         220 <domain> Service ready
         221 <domain> Service closing transmission channel
         421 <domain> Service not available,
             closing transmission channel
            [This may be a reply to any command if the service knows it
            must shut down]
          
         250 Requested mail action okay, completed
         251 User not local; will forward to <forward-path>
         450 Requested mail action not taken: mailbox unavailable
            [E.g., mailbox busy]
         550 Requested action not taken: mailbox unavailable
            [E.g., mailbox not found, no access]
         451 Requested action aborted: error in processing
         551 User not local; please try <forward-path>
         452 Requested action not taken: insufficient system storage
         552 Requested mail action aborted: exceeded storage allocation
         553 Requested action not taken: mailbox name not allowed
            [E.g., mailbox syntax incorrect]
         354 Start mail input; end with <CRLF>.<CRLF>
         554 Transaction failed

TBS> Is not it possible, that some error on the SMTP server cause this
TBS> error message?

Yeah sure, but in that case you'd never be able to send a message.
