Thank you very much for writing. No, that doesn't change anything. (I didn't see the "Other Writing Systems.")

After about 20 years now, I'm going to give up and quit using Thunderbird I guess, and switch over to Mac Mail — mainly because of typographic issues (default sans-serif now, plus no smart quotes).

So now I need to know these things:

How do I get Thunderbird to stop downloading emails? I want to read emails only in Mail. Do I have to delete my Thunderbird account entirely?

I have a client to whom I email stories I've edited in Word, and because Mail adds space between the paragraphs, I would like to be able to SEND ONLY to this client using Thunderbird. If that's not possible, I hope to find out how to stop Mail (or Word) from adding extra space between paragraphs that's not visible when editing in Word ...

Sigh.

Thank you very much! I found "Other Writing Systems" and fixed that, and now all messages have serifs, so far.

Haven't gotten to the POP bit yet ...

I'm on a Mac, so when I paste a Word doc without formatting (Command Shift V) into MAIL, 2 extra blank lines get added between paragraphs (beyond the one blank line I want there). Same thing happens when I use the simple Command V.

When I paste a Word doc into Thunderbird using either method, everything is correctly spaced and sized.

I would eventually like to switch to MAIL permanently, but will have to solve the Word pasting thing first, because that's how my main editing client likes to receive it.

Until then I'll have to stick with Thunderbird for mailing to this client, which I guess means I'll have to keep RECEIVING emails in Thunderbird too. And I would be happy enough with that IF ONLY Thunderbird could automatically make smart quotes ...

Sigh.
