TB creates by itself a subfolder of INBOX called "Posta in arrivo" (Italian localization for Inbox), and then a folder "Cestino" (Trash) within "Posta in arrivo".
Both are empty of messages.

Reproducible: Always

Steps to Reproduce:
1. log in to an Fastmail.fm account
2. eventually refresh folder list (subscribe)
3.
Actual Results:  
Unwanted and unnecessary folders are created

Expected Results:  
TB should create only folders it is requested to

I cannot determine if the issue is about TB or Fastmail or about interaction between them

can you provide a imap log as described at https://wiki.mozilla.org/MailNews:Logging#Windows ?

I tried to keep the log as short as possible (just open TB, go to INBOX and exit)

I believe that the problem could be related to my "sent mail" policy.
I set TB in a way that it save my sent mails in INBOX

(config editor has "Copy" function. please attach data as text data)

If this setting, root-level Inbox is ordinaly used for fcc folder(sent folder).
Do you set "IMAP Server Directory:" of Server Setting/Advanced to "Inbox"?
If so, meaning of the fcc setting is Inbox.INBOX, and Inbox.<localized name of Inbox> can be created, if localized build and if folder hierarchy delimiter is ".".
It's already know phenomenon/issue.

I did not touch that field (the "IMAP Server Directory:" one), this is actually blank in my configuration.

No "IMAP Server Directory:" case.

Next is seen in log.
> 9 list "" "INBOX.Posta in arrivo/Cestino"
> 9 OK Completed (0.000 secs 1 calls)
> 10 create "INBOX.Posta in arrivo.Cestino"
> 10 OK Completed
> 11 subscribe "INBOX.Posta in arrivo.Cestino"
> 11 OK Completed
> 12 list "" "INBOX.Posta in arrivo.Cestino"
> * LIST (\HasNoChildren) "." "INBOX.Posta in arrivo.Cestino"
> 12 OK Completed (0.000 secs 2 calls)

Same as one of phenomena in bug 531566.
"/" is used by Tb in some situations, even though folder hierarchy delimiter of IMAP server is "."(period).
And, "localized folder name of Tb" is used for IMAP commands("9 list" of above log data)  by localized Tb in some situations, even though non-localized/correct folder name is set in prefs.js.

confirming based on log data.

Comment 9

[Anselmo Canfora]

Setting to zero length string the "personal domain" field (set to "INBOX" by Fastmail) and disabling the option "allow server to override these domains" on account advanced settings can avoid the problem.

No, but I've only been using FM for 3-4 years.

Gene, would you say this issue is likely gone? And if not is the log of any use?

Hard to say without a fastmail account localized to, e.g., IT.
All I see in the log is TB creating the subfolder of Inbox that the user is reporting.
But if no reports of this nature in 6 years, I'd say something has changed (at FM or TB) that has fixed this. Either that or no one is using non-EN FM with TB.
