SMTP failing from one account only (not a port 25 issue)

[EMS]

User getting the following when sending mail...

An unknown error has occurred. Subject 'hjghjghjg', Account: 'mail.removed.co.uk', Server: 'mail.removed.co.uk', Protocol: SMTP, Port: 25, Secure(SSL): No, Error Number: 0x800CCC0B

I noticed he's on Windows "ME" - so in between laughing and pointing I setup a new test pop account in his control panel and configured the account on my own PC here.

The same error happens for me.

I can send mail fine using other acounts on the same server.

Its not a port 25 issue with his isp and all mail client settings are correct, including SMTP authentication.

The only factor I can think of that may have had an influence is that the customer has been using neomail on these accounts for about a month and this is the first time his mail has been set up from a mail client .

Ive run the usual scripts to no avail.

Any ideas ?

Same error here. And it is not a ISP/provider error.
Other accounts from other domains (and servers) works fine. Only get this error in only onde domain in (i gess) my cpanel box.

I send emails true neomail/horde/squirrel normaly. This error is hapens only in the outlook.

And i try all - restart server, reinstall cpanel, reinstall exim, etc etc etc ...

Hummm...

I have this error in my /var/log/exim_rejectlog:

2004-10-18 15:04:01 H=200164098016.user.veloxzone.com.br (tihost) [200.164.98.16] F=<webmaster@insidehost.com.br> rejected RCPT <alexandre_duran@yahoo.com.br>: 200164098016.user.veloxzone.com.br (tihost) [200.164.98.16] is currently not permitted to relay through this server. Perhaps you have not logged into the pop/imap server in the last 30 minutes or do not have SMTP Authentication turned on in your email client.

Most likely he's not using SMTP authentication

Most likely he's not using SMTP authentication

I try this, but dont work.

I found the solution (dont ask why ) - this account is set to demo mode.
I configure this with no demo mode and now this send email normaly.

Try this EMS - see if this accout is set to demo mode. Works here !
