[newbie] Have I got a Virus ?

[John Richard Smith]

All my Kmail emails have become blocked .   every time I go to send an email I get the usual error message:-   Command RCPT Response 550 relaying to < [EMAIL PROTECTED] > Prohibited by administrator. message will stay in outbox,blah,blah,blah, transport protocol smtp://mail.mnopq.net25   and yes I know perfectly well that this usually means you have made an error in the email composition, perhaps for instance you might of omitted to insert an email address, but not this time, if there remains an error with any of the emails it is well hiden,and in anycase I moved the leading emails off the outbox so as to remove them one by one to see which one was causing the delay, eventually I had none left.   this problem arose after having received an email from a relative who complained of just the the same problem in their emailer(Outlook express), and the funny thing is that when I took the parcel of emails I had waiting to go, off one computer via a floppy, to another the same result happened in yet another Kmail emailer.   All this I tried in root as well to see whether I had a permissions problem , it didn't make any difference.   Finally, I resorted to my own version of Outlook Express,against my wishes.   John     John Richard Smith
