Čemu otvarat nove foldere za svaki account kad se to može i nekorištenjem globalnog inboxa, kako ga Thunderbird zove.
Na Yahoou se ne plaća POP3 pristup, treba ti samo YPOPs! i onda ga prema ovim uputama namjestiš:
Click Tools-> Account Settings
Click Add Account button.
Choose Email account. Click Next
Type name and email address in the boxes. Click Next
Choose POP and type 'localhost' as the incoming server.
Depending on your preferences check or uncheck Use Global Inbox
Click Next. If your username is not already there by default, add it.
Click Next. Add the way you want your Account Name to look in Thunderbird.
Click Finish.
Now scroll down to the bottom of the Account Settings pane and click on Outgoing server (SMTP).
Click on Advanced. Click on Add.
Type 127.0.0.1 as the outgoing mail server. Port default is 25.
Check Use name and password. This is Thunderbird’s way of enabling authentication.
Type your Yahoo user name as username@yahoo.com.
Click No to Use secure connection and then OK twice.
Click OK to the Server Settings window.
Now get back into Account Settings
Go back to the Server Settings of you Yahoo Account in the Account Settings pane.
Do not check Use secure connection (SSL) or Use secure authentication.
Click on Advanced.
Choose where you want your emails to go in the POP tab.
Click on the SMTP tab and click on the drop down menu and select 127.0.0.1:25
Continue modifying any of your preferences in the account and then click on OK.
The first time you try to access the account, Mozilla will ask for a password and if you want Mozilla to remember the password.
Što se tiče formatiranja diska i spremanja postavki, dovoljno ti je folder od svakog accounta premjestit na drugu particiju i onda kod nove instalacije, Thunderbirdu samo pokažeš gdje se nalazi taj folder i to je to. Možeš koristit i MozBackup, ali meni je ovo s premještanjem foldera bolje budući da ne reinstaliram Windowse nego samo vratim image.
