I think the title says it all.
I have a 25GB U1 account and I like the option provided in Thunderbird to upload large e-mail attachments to YouSendit.
Is there a way to use U1 instead of YouSendit?
I could obviously publish the file via U1 and copy the weblink into the mail body. But I'd like to be able to have the step happen automatically when files exceed a certain size. Having said this, I kind of expected to see U1 as an option in the Thunderbird Edit->Preferences->Attachments menu.
