Temporarely disable an account
I have about 12 email-accounts in Thunderbird. Normally I download all mails by clicking "Get all new messages". But I have 2 accounts which are working only over modem-connection (depends on my email-providers). On PC's where I don't have a modem I want to temporarely disable these 2 accounts because otherwise I get an error-message. Is this possible in a setting or option?
