someone must have had this before. Anyone? :S
I found this on the net, dunno if it helps but may point you in the right direction:
I recently got this error when trying to send an email in Outlook. The culprit? Apparently this occurs when a server is expecting to receive mail before sending. This is usually results from server authentication priorities (for example, you attempt to send mail before your "spam filter" has finished its receiving process.)
Edit- And this:
The 503 error code means some commands were executed in the incorrect order.
From RFC 821:
"If the commands in a transaction are out of order a 503 failure reply must be returned and the receiver-SMTP must stay in the same state."
So in this instance, a RCPT command wasn't sent before the DATA command. The SMTP server is just sitting there waiting for a RCPT command, while your email client is sending a DATA command.
Check the address you're sending to/from is correct, failing that try using a different email client.
And another may help:
Possible Solutions
Pop before SMTP -- Run a check for new messages (F9 key in Outlook) before sending your message and restart and rerun your spam filter application. Your IP address is entered in a relayhosts file, allowing email to be sent from your address for up to half an hour.
If the problem still persists check "my server requires authentication" to authenticate automatically. With this setting you can bypass the check above and send mail without having to "pop" your mail box first. You can also try changing the outgoing port from 25 to 26, since some ISP's block this port.
Finally, if using a mail screening utility such as Mail Washer, you may want to disable the "automatically check at intervals" setting and check mail manually. If the system checks mail while you are sending you may get this error.
Check Your Mail Server
If none of the above work we recommend contacting your hosting provider. Your mail services account needs to be set up properly (associated with the right user name, etc.). We encountered this exact problem when switching hosts once - the mail server configuration got goofed up, and none of the above solutions worked. In the interim (until settings are fixed by your hosting provider) you can adjust your outgoing mail server to reflect that which your ISP uses, which should let you send mail again through your local client (Outlook, but not from the server (Webmail)), until the problem is fixed.
