By default WorldClient uses the “Date” header of inbound mail rather then the time/date when the message was received. This is normally desired as it allows the receiver to see the order messages were sent, even if some mail was delayed in transit.
However, with spammers and other nefarious individuals being able to tamper with Date headers, this is not always desired and some even consider this a security issue in that it allows a sender to lie about when a message was sent.
There is a switch in WorldClient to tell WorldClient to use the timestamp when the message was retrieved, rather then relying on the date header, if you so desire:
In the WorldClient.ini file, [Special] section, look for the following key:
If you set that to “Yes” then it will use the date your mailserver received the message rather then the Date header. However, in the case of MultiPOP’d mail, it will actually list the date/time that MultiPOP retrieved the article, so it loses some effectiveness.
Note that if you change this switch, it will only apply to newly received messages. Messages which have already been received will still use the “Date” header. Delete your “message.idx” files to cause WorldClient to rebuild it’s indexes.
Also note that this only applies to WorldClient, POP mail clients can do whatever they want, and IMAP exposes both dates to clients allowing clients to display either or both dates, depending on the client’s capabilities.
