使用 offlineIMAP 仅下载 gmail 的收件箱

因此我的 offlineimap.conf 如下所示：

[general]
accounts = Gmail-raub

[Account Gmail-raub]
localrepository = Gmaillocal-mine
remoterepository = Gmailserver-mine
synclabels = yes
# This header is where labels go.  Usually you will be fine
# with default value (X-Keywords), but in case you want it
# different, here we go:
labelsheader = X-Keywords

[Repository Gmailserver-mine]
#This is the remote repository
type = Gmail
ssl = yes
remotepass = super-sercret-password
remoteuser = [email protected]
sslcacertfile = /etc/ssl/certs/ca-bundle.crt
ssl_version = tls1_2

folderfilter = lambda folder: folder in ('[Gmail]/Drafts')

[Repository Gmaillocal-mine]
#This is the 'local' repository
# type = Maildir
type = GmailMaildir
localfolders = ~/mail/gmail_offlineimap

通过上述设置，我可以下载草稿，但如果我用 [Gmail]/Inbox 替换 [Gmail]/Drafts 文件夹过滤器条目，它会照常启动

然后验证并列出我拥有的所有不同邮件文件夹。然后根据我的文件夹过滤器设置将它们全部过滤掉。但随后它只是关闭了连接：

为什么它会终止连接？它不像 [Gmail]/Inbox 吗？我也试过了

# folderfilter = lambda folder: folder in ('[Gmail]/INBOX')
# folderfilter = lambda folder: folder in ('INBOX')

并且它们中的任何一个都会导致不同的错误（但它们之间是相同的）：

ERROR: getfolder() asked for a nonexisting folder 'INBOX'.

答案1

它不“喜欢” Inbox，因为收件箱的名称全部大写，名为

INBOX

使用一个小的 Python 脚本进行尝试

import getpass, imaplib

M = imaplib.IMAP4_SSL('pop.gmail.com', 'imaps')
M.login('[email protected]', getpass.getpass())

ret, data = M.select('INBOX', True)
print(ret, data)
M.close()

M.logout()
