BT Broadband Question

[stampede]

All,

It has become increasingly more difficult, over the last few days, to be able to send from my MS Outlook to my email host over BT Broadand.

I get a message along the lines of:-

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

Subject: RE: xxxxxxx
Sent: 15/05/2006 21:27

The following recipient(s) could not be reached:

'abc' on 15/05/2006 21:27
553 sorry, that domain isn't in my list of allowed
rcpthosts (#5.7.1)"

Someone mentioned that I have to register my host with BT in some way to allow my emails to be transfered to my email server.

Does anyone know how to do this as I'm buxxerxd if I can find it on the BT site.

Thanks in advance.

This is outbound mail isnt it?

Didnt think that the MX record would change that.

I'm no mail administrator mind you...

Is that message coming from your host server, which I assume is the smtp server you're using from Outlook? or is it from the recipients server?

Are you sending 'from' a non-BT domain? If so, yes you will need to get the domain registered with them as allowable if you're sending using BT's SMTP servers. This didn't used to be the case, but they're implementing it gradually.

Or set the 'from' address to your BT one and use 'reply-to' instead.

I'm sending from my MS outlook on my home PC over the BT broadband to my SMTP server and then onward into the ether.

The message comes back as soon as I try to send.

Thanks for the interest all.

Neil,

This is what I suspected, and as you say, I'm effectively sending using BT's SMTP. I don't want to set my "from" address to BT as I have several "work" related accounts that I want to maintian autonomous. I just want to use BT as an ISP.

Do you know how I go about getting my domains registered?

OK, if I'm reading this correctly Outlook is using your remote SMTP and it isn't letting you as it won;t allow relay from a BT connection which is only right and proper.

There are several things you could do, but moving your domains to BT is not one I'd recommend.

1st thing I'd do is check if you current domain hosts have a secure relay server, which requires you to authenticate, This is by far the best solution IMO, as it means reverse lookups will be consistent, which is good.

Assuming you run XP you could use the SMTP server that comes with XP. Start => control panels => add remove programs => add remove windows components => IIS => details => smtp service. Then tell outlook to use 127.0.0.1 as the SMTP server.

The downside of this method is that some companies will reject your mail as spam.

I haven't got a note of the page unfortunatley, suffice to say it took a fair bit of browsing & googling to uncover it

The following is a guess with lots of MTA geekery in it, although I am no mail admin. Read at your peril

It looks like your recipient's email host has a misconfigured MTA running qmail. My guess is that DNS says that the MX for "their-email-address.com" is "mailserver-01.com" but mailserver-01.com is saying that it knows nothing about their-email-address.com and wont accept email for it. qmail (mail server software) requires a list of all the domains it accepts email for in a file called /var/qmail/control/rcpthosts, it would seem your recipient does not appear in this list on the mail server that is supposed to handle their mail.

Not a great deal you can do I think, I do not think it is generated by the BT mail server not liking the domain you are sending 'from' as it is not a sensible message to give if the sender address is wrong.

If you post the entire bounce message including full headers (most important bit) it might give a few clues. Remove their email address and yours if you wish.
