weird email error

[Squawk7777]

Send an email to my friend today, and it came back as undeliverable. It said:

[email-address]:550 relay not permitted [priv_1]

Squawk7777,

Mail relaying is the practice of sending mail to a remote mail host other than direct to the recipient host itself or to the host specified in the Domain Name System (DNS) by the MX resource records for the recipient address.

Until recently, most mail hosts on the Internet freely permitted relaying to ensure that the SMTP mail transport system could route around temporary losses of connectivity and other network related problems. However, unscrupulous junk mailers eventually learned to abuse that trust-based system by offloading their messages onto any mail service which offered them the opportunity of hiding the true origin of their messages. It is becoming exceedingly rare, therefore, to find a mail host which offers to accept mail for delivery to anything other than recipients which it regards as being local to itself.

Uncontrolled mail relaying places the viability of your own mail service at risk. If detected and placed on a black list, many mail destinations may refuse to accept mail directly from your host and may also refuse to deliver mail to your host. Further, whilst it is very easy to get on blacklists, getting removed from blacklists can be inordinately difficult, particularly where private schemes are involved. Consequently, understanding the concept of mail relaying is vital for all responsible Internet mail administrators.



Take Care,

Richard

So, assuming this becomes more commonplace - and it does seem to be quite a good thing, what can we do about it?

Do we keep sending until we get it through? Thereby increasing e-mail traffic.

There used to be those messages saying "unable to deliver message to its destination but will continue to try for the next 48 hours. No action required by sender." Haven't seen that for ages.

It probably indicates a mis-configuration somewhere. Is your mail program (Lookout... sorry Outlook ?) configured to use your ISP's mail relay ?

[SeldomFixit]

If you have recently moved to a new provider, you probably received a new user name. Did you then change that user name to one you found more suitable ?
Chances are you need to reconfigure your mail settings to reflect that change. Set up an account with your new name and all should be well again. If not, then no clue sorry.

It's a spam prevention measure as far as I know - can happen if you try and send an email to the wrong server - for example [email protected] to smtp.blueyonder.co.uk. It will reject with that kind of message.

Do you have two ISPs?

If your Email account is with Pipex for example and you have a BTOpenworld connection for cheaper surfing, you won't be able to SEND mail via your Pipex settings to anyone, when connected to BTOpenworld, however you will be able to connect to your POP3 server and receive Emails. Could this have been your problem?
