Hello! I've just upgraded to CiviCRM 2.0.1 and some of my emails never reach desired addresses because of the following message on their server: *Recipient address rejected: Invalid sender *(in reply to RCPT TO command)).

I assume that it's because of the VERP and the ISP that reported this error message suggested me to switch VERP to an existing email address.

From: bounce.1.4.3.1b5695055b86de78cf47bd3a2c9fd5560d12d97a-name=domain.com@domain.com
To: existing_username@domain.com

How can I solve this issue? Any suggestions?

I guess this would do the trick:
        $headers = array(
                         'Reply-To'  => $this->from_email,
                         'Return-Path' => $this->from_email,
                         'From'      => "\"{$this->from_name}\" <{$this->from_email}>",
                         'Subject'   => $this->subject,
                         );


your best option is to hack the code at: CRM/Mailing/BAO/Mailing.php, line 861

Code: [Select]

        $headers = array(
                         'Reply-To'  => CRM_Utils_Verp::encode($verp['reply'], $email),
                         'Return-Path' => CRM_Utils_Verp::encode($verp['bounce'], $email),
                         'From'      => "\"{$this->from_name}\" <{$this->from_email}>",
                         'Subject'   => $this->subject,
                         );

and fix the reply-to, return-path as needed. Note that changing them would invalidate the bounce / reply to parts of the code. There is also a bug with the length of the VERP addresses we generate ( > 64 chars). This will be fixed in 2.1
