Are you trying setting up your mail accounts as POP or IMAP instead of Spool.

I have never seen a instance in this forum of someone with your issue actually meaning to use the spool file. A Linux/Unix only feature. Almost all folks need to use IMAP or POP to retrieve their mail from the provider.

I have tried setting up email account on both seamonkey & thunderbird using both POP & IMAP but to no avail I can't get rid of mail spool error

Please explain in detail the steps you're doing when setting up the account.
