SMTP Error: SMTP error: Failed to add recipient - Dev

18 Oct 2006


      Hi,
I have (had) some users getting the following error:
SMTP Error: SMTP error: Failed to add recipient 'random@email.address'
It happens with the same users continuously.
So I tried adding some debugging to the function that caused this error,
and changed this:
// set mail recipients
   foreach ($recipients as $recipient)
     {
     if (PEAR::isError($SMTP_CONN->rcptTo($recipient)))
       {
       smtp_reset();
       $SMTP_ERROR .= "Failed to add recipient '$recipient'\n";
       return FALSE;
       }
     }
into this:
// set mail recipients
   foreach ($recipients as $recipient)
     {
     $error = $SMTP_CONN->rcptTo($recipient);
     if (PEAR::isError($error))
       {
       smtp_reset();
       $SMTP_ERROR .= "Failed to add recipient '$recipient'\n";
       $SMTP_ERROR .= "SMTP error: '".$error->getMessage()."'\n";
       return FALSE;
       }
     }
and all of a sudden the problem is gone for the users.
Is my pear install broken? Does PEAR::isError() have a problem with
$SMTP_CONN->rcptTo() somehow?
