I've been using Mozilla Thunderbird at work with our Exchange server and it works great. However, when I create an email to go to the Internet, my Exchange & Postfix MTA complain about a forged message-id: 550 5.7.1 forged name in Message-ID: header: In KMail, I've gotten around this problem by changing the Message-ID Suffix option to something the server likes. However, I cannot find such an option in Mozilla Thunderbird. Does such an option exist and if so, where do I change it? I have no qualms about editing the about:config file if need be. Thanks in advance. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
