Continuing my saga ... After collecting vast quantities of old email
repositories into one place on my NAS, I chose to start with the "easiest"
one: The Thunderbird installation on my *indows laptop. I managed to do this
by opening two instances of Terminal (one to help me keep track of the long
path statements and the other for the heavy lifting). Then I moved just that
one Profiles folder from NAS to a partition on a slave hard drive mounted in
the desktop installation of Trisquel. That folder has been set up to keep
track of my stored emails according to the source ISP account from which I
originally pop'ed them down to the laptop. I used mv /sourcepath/filename
/destinationpath/filename01 and so on. Except for a glitch having to do with
Thunderbird filenames containing spaces, this went OK.
Except for one ISP which I no longer use: Trisquel's Icedove had no account
set up for that ISP. Let's call it popmail.chopchop.net. There are many
files and mini-folders in this fairly well organized Inbox, but Icedove won't
recognize popmail.chopchop.net as a valid folder, even though Terminal &
Trisquel are happy with it, as they are for other accounts which I had
already set up when I installed Icedove.
So far I have just tried to set up this popmail.chopchop.net account as a
"MoveMail" account ... as it doesn't seem right to use it as a popmail
account ... but Icedove says "unable to locate mail spool file" when I try
"Get Messages" and it won't accept popmail.chopchop.net as the folder under
which this myriad of messages is organized.
Three other accounts under Icedove have mixed results: One has two Inboxes,
called Inbox (original to the Icedoce installation) and Inbox01 (which is
where I have put the Thunderbird emails) and this one is completely
successful; A second account has two inboxes which are labelled strangely, as
Terminal sees them as Inbox01 and Inbox02 (both my settings) whereas there is
no folder called just Inbox. Icedove initially had two such folders called
Inbox (original to the Icedove installation and containing emails OK) and
under that a subfolder called INBOX (greyed out and inaccessible, even after
I renamed it to Inbox01) in this second account. A third account looks like
the first account, but its Inbox01 apparently is empty, even after I checked
the active profile and found ext-based emails there with sudo cat Inbox01.
The situation with the second account did not improve when I changed the
names, Inbox01 and Inbox02, to Inbox and Inbox01, respectively.
My /dev/sda6 partition is formatted xfs and is mounted during startup at
/home, which is where these files are.
Apparently, I did something right with the first account that isn't working
with the other two accounts.
