Remember I'm smiling as I say this. Traditional IT users trap, "I didn't 
do it" from both sides (I really am smiling).

The host is thinking it's on the software side. I'll pass on their 
tidbits and then I add some things I've teste as well.

The first message I got from them was that they had found a log entry 
and had a comment:

2015-01-25 13:39:04 dovecot_login authenticator failed for 
173-31-180-217.client.mchsi.com <http://173-31-180-217.client.mchsi.com> 
(#localhost.localdomain) [173.31.180.217]:47843: 535 Incorrect 
authentication data

"The above log example indicates a login failure due to "Incorrect 
authentication data". This could be use of a bad password, or it may 
have to so with an incorrect configuration on the client side."

Later, they also commented on Andrej's thought "From the available data, 
it looks like this is a server issue. There is no way a server can not 
understand "AUTH" command after it told the client that it supports 
authentication."

with this:

"Please know - if that were true, (There is no way a server can not 
understand "AUTH" command ) then no email clients would be able to 
connect to any of our mail services."

Basically they are saying that they have mail traffic moving and an 
"AUTH"  working this badly would cause chaos.

Now for my observations trying to get set up. First I have set up this 
hosted email account and a gmail account using Claws on Windows 7. Both 
accounts can send mail and receive mail no problems. These two accounts 
and others I have all work in Thunderbird on both Windows and Linux as 
well (the one's on Thunderbird Linux were set up the same day just 
before and after I'd started trying Claws). So I think I've got all my 
username, password, settings pretty well in hand.

It's only when I try to use Claws on Fedora 20, LXDE desktop (I did try 
once from KDE). I took screen captures on the Windows Claws account 
settings, all 8 screens, and used that to enter the same settings on the 
Linux Claws. I've also re-entered user and passwords (I typed passwords 
in  on the Windows side where it worked, so I at least type them in 
right there). There is also a "saved passwords" addon for Thunderbird 
which allows one to copy the user and password out of an account which I 
used to get text to paste into Claws. All these things failed to get me 
going with Claws on Linux.

At this point, I've passed on the Windows (working) and Linux (not 
working) network logs for my hosted email account when I sent the 
original email. So here's the working (windows) and not working (Linux) 
network logs captured out of Claws when I tried to send mail using 
gmail. It's a might different than for my hosted email, but it fails at 
that AUTH LOGIN on gmail just like the other (I X'd out my mail info):

If there's anything else I could try, just let me know. I kind of like 
the flexibility and responsiveness of Claws and would like to get over 
this hump!
