I am moving web site from one host company to other.
I have few user accounts which use Squirrel Mail.
The apparent data are in folders like /home/user_name/mail
Another host has Web-based email reader called "Webmail" which has the same icon as "Squirrelmail".
How to move data?
What is the data format?
Which program reads these data?
The data - content of /home/user_name/mail folder is a directory tree.
I backed these trees up, but don't know what next?
