If you can use IMAP, then do as war1 suggested, but if not, then use the &quot;Mail Redirect&quot; extension and redirect the mail to yourself. &nbsp;All the headers you need will remain intact and the mail will look like it was sent to you originally.<br />

I had configured a POP account in thunderbird, due to default setting POP fetched all the message from my email account and it didn't leave any message copy on the POP server in my email client.<br />
<br />
Is there a way I can sync[transfer all mails back to my POP server] POP server and my thunderbird client ?

Thunderbird is an email, newsgroup, news feed, and chat (XMPP, IRC, Twitter) client that supports POP and IMAP and LDAP address completion. The vanilla version is not a personal information manager, although the Mozilla Lightning extension adds PIM functionality. Thunderbird can manage multiple email, newsgroup, and news feed accounts and supports multiple identities within accounts. Features such as quick search, saved search folders, advanced message filtering, message grouping, and labels help manage and find messages. Thunderbird incorporates a Bayesian spam filter, a whitelist based on the included address book, and can also understand classifications by server-based filters such as SpamAssassin. Extensions allow the addition of features.
