As I wrote earlier, I can't follow the instructions in that link. It says to mouse over the Settings icon and then click on Settings. Settings isn't one of the options I see. See 5 posts up.

Edit: Since we're now on p. 2, let me be more specific. See my post of 4:41 a.m. on the 10th.

There's something else going on. After I switched to New Mail, I didn't see what I was supposed to, but I did eventually get to Add a Mailbox. However, the choices were Yahoo Google Outlook.com AOL and other. When I clicked on other, I got a message saying that new providers will be coming soon. There was no opportunity to input my own provider. The Yahoo tech confirmed that those 4 are the only choices at this point.

I don't think you want to Add a Mailbox in that way - that looks like the add-account dialog in a mobile mail app. Log into the Yahoo account on the Yahoo website through your browser, not with the Yahoo mail app, and follow these instructions:

https://help.yahoo.com/kb/sln28342.html

or ask the Yahoo tech how you can accomplish this (send them the link).

Apparently, when I somehow was able to partially enter the info for 012, that became an additional send-only address. That's what I found by following the steps in the link you provided in your last post.

Now, how do I set up 012 at Yahoo to receive my 012 e-mail?

And a big thank you for staying with this and continuing to guide me.

Do you want to have the 012 mail collected by the Yahoo account? I though the original request was to be able to send from the 012 account through the Yahoo smtp server, but still download 012 mail through the 012 account. But if you want to have 012 mail collected by Yahoo, look here.

My original request specified that I wanted to access 012's servers.

As I wrote earlier, I'm not seeing what the instructions at the link you gave say I should.

1) Mousing over the Settings icon yields nothing. I have to click on it.

2) When I do click on it, there's no Settings option. See image.

3) When I click on More Settings, Mailboxes, Add mailbox, The only options, as I've written before, are Yahoo, Google, Outlook.com AOL other. Clicking on other produces the messages that more providers are coming soon. No opportunity to input information for 012.

It looks like Yahoo can't collect mail from providers other than Google, AOL etc. This is not a limitation with gmail or outlook.com, and possibly other mail providers. But, as I said before, you should still be able to receive your 012 mail anywhere; it's sending mail that requires another provider's smtp server.

Are you saying that if I leave my incoming mail settings just as they are, TB will still connect to 012's POP server when I'm in NY and retrieve my mail?

As for outgoing mail, all I have to do is change the TB SMTP setting to Yahoo's SMTP server and (now that I have 012 set up at Yahoo as a send only address) mail that I send out from TB in NY will get sent showing my 012 address?

I suggest you try to collect your 012 POP mail when connected to another network. I can't read the Hebrew description of the POP settings, although you say it's STARTTLS on port 110. Some ISPs allow POP downloads on other networks as long as there is password authentication.

If you've added the Yahoo account to TB, and added the 012 account as a Yahoo send-only address, then you should be able to send from TB through the Yahoo smtp on any network, including your 012 network.

I did add the Yahoo account to TB, but - and it appears that I still haven't completely understood - I thought that that wasn't necessary. As I just wrote, I thought all I need to do is change the 012 SMTP server to the Yahoo SMTP server.

If I'm in NY connected to Spectrum and I send through a Yahoo account set up in TB, how will Yahoo know to treat it as 012 mail?

It may be sufficient to add just the Yahoo smtp server in Tools/Account Settings/Outgoing Server (SMTP). I haven't tested it. The important thing is that when you select the 012 account in the left pane of Tools/Account Settings, Outgoing Server (SMTP) in the lower right pane is pointed to the Yahoo smtp.

If you send through the Yahoo server from the 012 account, recipients should see it as coming from the 012 address because you added it as a send-only to Yahoo. You can test this before you connect to Spectrum or any other network.

I changed the 012 SMTP server to Yahoo's. This is the message I got when I tried to send:

An error occurred while sending mail. The mail server responded: Requested mail action not taken: mailbox unavailable. Please verify that your email address is correct in your account settings and try again.

Edit: Although I thought it was ridiculous, I changed my username in TB for the SMTP server from myusername to myusername@yahoo.com, and it turns out that that was indeed the problem.

Bottom line: Outgoing mail works. Since I have no way of connecting to another ISP while I'm home, I'll have to wait until I'm in NY to make sure that I can retrieve my incoming mail from 012. I'll let you know in about a week. In the meantime, again, my deep thanks.

sfhowes, everything works perfectly. I'm really, really grateful.

Thank you so much!

This is a new question but I'm posting it here because it's a(n unrelated) continuation of this thread. I brought along my profile folder because I wanted to replace the profile folder on whatever computer I'd be using and would be installing TB on. That way, just before I fly back home, I could once again save my profile folder to my flash drive and replace the old profile folder on my home computer so that no mail would be missing. (Please tell me that was clear.)

When I say that I brought along my profile folder, there actually was a glitch. It refused to copy Trash to my flash drive claiming there wasn't enough room, even though the file was some 5GB and free space on the flas drive was over 7GB. This was just before I left for the airport, so I had no time to try an alternative, such as uploading Trash to a file sharing service from which I could retrieve it upon arriving here.

However, after I installed TB and replaced the profile folder, I was pleasantly surprised to see that the messages in Trash were there. It was only today, 2 weeks later, that I actually needed one of those messages, and discovered that all the Trash folder contains are the subjects, the correspondents and the dates. The bodies of the messages are not there.

So, here's my question. When I return home, I don't want to replace the Trash folder, but I do want to add the messages I deleted while here to the Trash folder on my home computer. Is there a way to do that?

If not, the only alternative I can see is to move all the new Trash messages back to Inbox and then delete them when I've returned and replaced the profile folder on my home computer. (Is anyone following this?!)

I don't know why the Trash messages don't show, but if the account was IMAP, the Trash would have been synchronized between your home computer and the one you used abroad - no need to transfer the profile folder.

You could copy the Trash mbox file (the 5GB file named Trash with no file extension) from the profile folder to Local Folders on the home computer to keep it separate from the existing Trash folder.

Help/Troubleshooting Information, click Open Folder to open the profile folder; close TB before before making any changes.

POP account, not IMAP. Trash messages don't show because the file Trash didn't get copied onto my flash drive. Why it didn't, given that there was plenty of room for it, I don't know.

I also don't know why, given that Trash wasn't copied onto the flash drive, the Trash messages (sans bodies) are even showing.

But those are side issues. I'm not thrilled with your idea because that means that in the future, when I'm searching for some old message, I'll have to look in 2 different places. I guess I'll just move all the deleted messages from my stay here back to Inbox and delete them back home. Even if there are other solutions, it may be the easiest one.

Thanks very much for being there once again.

First, I suddenly realized why Trash wouldn't copy onto the flash drive. It was the (typically misleading Microsoft) message that threw me off. It said that there wasn't enough room on the drive for the file, even though there was way more space than the file's size. The drive comes formatted as FAT32, which has a file size limit of 4GB, while Trash was more than 5GB. Reformatting the drive to NTFS solved that problem.

Second, I refined my idea for integrating my messages deleted in NY with my Trash file here at home. I created a folder which I named To be deleted and moved all my NY deleted messages to that. Had I gone with my original idea of moving them all to Inbox, they would have gotten mixed in with the messages still in Inbox. When I got back home, I made a copy of Trash located on my home computer, replaced the profile on my home computer with that on the flash drive, copied the saved Trash to the new profile and then deleted everything in To be deleted.

I'm left with one annoying problem. Once I no longer had a need for To be deleted, I deleted that folder. But Thunderbird is unaware of that. When I search for a message in Trash, and hover my mouse over Trash, I have to choose between Trash and To be deleted, even though the latter no longer exists.

Any suggestions?
