got it.....short for 'mailhome".....
Sylpheed is executed for the first time, it automatically creates the configuration files under $HOME/.sylpheed/, and asks you the location of mailbox. The default is $HOME/Mail. If some files which are non-MH format already exist on the directory, you will have to specify another location.
Thank you Brian. I was having a minor panic attack as a family member has developed a pasion for hacking others email accounts.....and his initials are....MH
Back to Sylpheed.....appears to do what is says it does. It has loaded up two accounts from gmail without a murmur.
( For anyone else reading this topic...I am running Linux Mint 18.2, and Sylpheed can be found in software manager)
fed up with Windows antics...??
LINUX IS THE ANSWER
I USE LINUX MINT EXCLUSIVELY... NO DUAL BOOT, NO VIRTUAL MACHINE
Failure is not an option. It comes bundled with your Microsoft product.
