Hello
I'm getting the following error message using Smart Mailer PHP to a group of recipients;

Error sending e-mail

5.5.1 Error: need MAIL command
5.5.1 Error: need RCPT command

Please correct and try again

Any suggestions?

Martin

Hello Martin.

Does the message appear when you are using smartmailer with single recipient ?

Regards:Vulcho.

No, it's ok and it also works with 2 people in a small test list.

Hello Martin.

Here is the explanation and the solution to the error that you are receiving:

551 – User not local or
invalid address –
Relay denied.
(also called SMTP Error 5.5.1)

SMTP Error 551 : If neither the sending mail address nor
the recipient’s address are locally hosted by the server,
then the ISP’s servers may refuse to relay the message
on. Some ISPs implement this restriction to thwart spammers.

Error and solution example:

Quote

You have a domain that is hosted by
CrystalTech.com but your ISP is DodgyISP.com and
you try to send emails from your domain to

Neither your domain nor Yahoo.usa are hosted by
DodgyISP.com, as a result your email is not accepted by
DodgyISP’s mail servers and your mail server is returned
an SMTP Error 551. To correct the problem you have to
call DodgyISP.com and ask them to enter your domain
name as an allowed sender.
