This problem is generaly caused by a time out in the pop3 session and = as many pop3 clients delete messages after retrieving all of them (not = after retreiving each, for historical reasons); if session drop for any = reason, then next time the pop3 client retreive all the mails.
Main causes for time out are, combined or not, from most common to less common : - Client Anti-virus software : some are 'specialists' to break pop3 = sessions on slow links with large mails (or not), or with no rfc compliant mails (some spams) - Client computer busy - Client connexion busy (especially when sharing the connexion) - Bad mail that can cause some mua to hang - Server busy or Server side connexion congestion When you say "they will receive ALL 5 twice", do you mean that they = receive twice after ONLY ONE click on "check mail" without any error ?
