550 Administrative Prohibition

[Terry Bennett]

I suddenly seem to be getting this message:

Your message did not reach some or all of the intended recipients.

Subject:

The following recipient(s) could not be reached:

'[name of recipient]' on 11/07/2009 00:25

550 Administrative prohibition - relaying not allowed

This seems to be a PC based problem rather than anything to do with my ISP
as it is instantaneous as soon as I click on 'send'. I can no longer send
any e-mails using this account but using other accounts seems to be fine.

Any ideas?

Configure Outlook to authenticate to the SMTP mail host in the e-mail
account that you defined in Outlook.

Many thanks for the advice, but I haven't the first idea what any of that
means!

Could you tell me how please?

Sorry ... bit of a novice at Outlook!

Why would it suddenly have changed?

Hi. I'm a virgin.net customer and since this morning (Saturday 11th
July 2009) I have exactly the same problem. I DO authenticate against
the virgin mail servers and I've not changed my setup. I'm fairly sure
the issue here is because i'm not on a Virgin Media adsl or cable
connection, and it seems they've disabled use of their servers
entirely from outside. Great.

Just spoke to Virgin.net support.. "It's a known outage and will be
resolved by Monday"

Do you know how to look at the e-mail account that is defined in
Outlook? If so, go to More Settings. The SMTP server is the Outgoing
Server.

Some reasons for changes:
- You

configured Automatic Updates to automatically download and
install updates from Microsoft (rather than just notify you). That
means you permit Microsoft to change the state of your host whenever
they feel like it.
- You installed new software.
- You enabled e-mail scanning in some security product (anti-virus,
anti-malware, HIPS, firewall, etc). It did a program update and now
interferes with your e-mail client sufficiently enough to cause the
problem.
- Your e-mail provider decides to improve their security by requiring
off-domain users to qualify that they have permission to use their
resources. E-mail requires cooperation at both ends (client and
server). Just because your end didn't change doesn't means their
cannot.​

Many thanks Richard - ANOTHER outage on Virgin!!

 

[Terry Bennett]

Thanks for the further advice - much appreciated.

It seems from Richard's comments that this particular problem is probably
something at the Virgin.net end and it is expected to clear over the next
couple of days. I will keep your comments to hand though in case it
doesn't!

On the subject of the automatic updates to which you refer - how do I turn
these off? I have previously had problems with them and am not sure what
real benefits they bring.

Thanks again.

If course, that applies only if you, too, are a Virgin customer.
