I am transferring mail to an IMAP mailbox on my btinternet email account. Unfortunately, I keep receiving these errors:
The current command did not succeed. The mail server for account email@example.com responded: [SERVERBUG] APPEND Server error - Please try again later.
Connection to server firstname.lastname@example.org timed out.
Can anyboy tell me what might be the cause of this problem?
Is there a size quota for IMAP mailboxes?
Thanks. I am using Thunderbird 15.0.1 on Windows XP.
