Yes I can....

The same happens here.

I have to servers : exact same CVS and config files (same SMTP server) 
and we don't use pgp.

The only thing different is php :

server A : php-5.2.6.2.fc7

server B : php-5.2.5-5



I have no problem sending messages from server B.

Using server A, from IMP, compose a new message and add at least  two 
recipient. I get the following error when sending the message :

There was an error sending your message: Failed to add recipient: 
@mbpgroup.com [SMTP: Invalid response code received from server (code: 
553, response: 5.1.3 <@mbpgroup.com>... User address required)]



If I have only one recipient, the email is sent without any problem.



I found a dirty fix to my problem, but I don't know why it does work 
on one server and not the other one.



At the end of function _createMimeMessage  imp/lib/Compose.php

         return array('recipients' => $to,

+                     'to' => str_replace(', ,',',',implode(', ', $to)),

-                     'to' => implode(', ', $to),

                      'msg' => &$mime_message);



it seams that values in array $to ends with ", " and implode adds as 
well ", " which becomes ", , "

eg :

$arr = array();

$arr[] = 'email@email.com, ';

$arr[] = 'email2@email.com, ';

echo implode(', ', $arr); // email@email.com, , email2@email.com,





Then, from fonction sendMessage imp/lib/Compose.php



IMP::parseAddressList($email, true, true) returns an array with 3 
values insead of 2.



Can you reproduce the problem ?
