I run a large multi-list opt-in only bulk mailing service. We use Imail pop3/smtp services to send messages to our clients. Recently I have received complaints from users of the Netscape Mail product that they are receiving the same messages repeatedly. I investigated this and have isolated it to a problem with the header tag X-UIDL being left empty. When the X-UIDL tag is empty the client seems to repeatedly request the message from the server without removing the message on the server. Upon further investigation at http://www.faqs.org I have learned that the anti-spam RFC has indicated that the X-UIDL tag will never be a formal part of the message header and is not likely to ever be adopted within an RFC as a viable tag line. Do any of you have an opinion about the X-UIDL header line and its use. Is there a way to turn off this header entirely? Has anyone else experienced this problem?
