Currently I am using:
TheBat! on Windows 10 as my main email. I have some mixed feelings, but overall it is OK.
Eudora has its own historic 50 GB archive that I use for searching.
However, these are a bit cumbersome for Biz usage, so many accounts, forum email etc.
Yes, I think you can run two instances of these programs with different target files, but I usually avoid that.
So now I am putting my biz email in a special redundant spot (using Gmail forwarding and filtering/forwarding) for POP download:
To have a special ultra-light Biz email spot on my Windows Puter client.
POP Email spot - paying a few dollars a month is fine, e.g.
.............................Fastmail, Runbox, Zoho, Posteo. 10 more
Fastmail, often the leader, surprised me with an App Password which felt clunky and I could not get it set up easily with Claws or EmClient
Runbox set up right away. it looks like a special might give me two yeas of Basic for about $35.
Since this is a POP download box, daily, hourly, es suficiente.
..........................Claws, EmClient, Mailbird, Postbox, Thunderbird, Becky, Foxmail, Pegasus, Barca(Poco)
The Email program should still be developed, and have nice RTF-HTML editing, stable, decent filtering and searching, and it would be nice if it had virtual folders (as TheBat! has but Eudora does not). Forums like that available on TheBat! and Eudora are helpful. Oh, decent on flexible spoofing or reply:to capability.
Claws does not seem to have RTF editing, not even with a plug-in, at least on the new Windows version.
Your thoughts. Especially on the Windows email client.
Well, I do have a Linux system coming in tonight ($30 Craigslist special, 6GB, Linux Mint 18).
