I can't download my POP3 email from BT Yahoo! I get an error message 0x80042110 that says: "The number of messages returned by the STAT command does not match the number of items returned by the UIDL or LIST commands. Contact your POP3 or Internet service provider." Yahoo says it's nothing to do with them and they don't understand what it means. Bernard Meakins
Generally it means that you have one or more corrupt messages in your mailbox, so you need to log on via the web and delete it - or delete as many as needed until you find it! The topic is mentioned on Yahoo! Answers.
If you cannot log on to a mailbox via the web, MailMaint (www.magsys.co.uk/mailmaint/) software provides another way to do POP3 mailbox maintenance.
