如何在 Crontab 中正确运行 OfflineIMAP

Question

安装了 Fedora。

# cat /etc/redhat_release | awk ' { print F "> " $0; print ""; }'
Fedora release 14 (Laughlin)

从 yum 安装了 offlineimap，因为这些天我很懒。

# yum info offlineimap | awk ' { print F "> " $0; print ""; }'

Description : OfflineIMAP is a tool to simplify your e-mail reading. With
            : OfflineIMAP, you can read the same mailbox from multiple
            : computers.  You get a current copy of your messages on each
            : computer, and changes you make one place will be visible on all
            : other systems. For instance, you can delete a message on your home
            : computer, and it will appear deleted on your work computer as
            : well. OfflineIMAP is also useful if you want to use a mail reader
            : that does not have IMAP support, has poor IMAP support, or does
            : not provide disconnected operation.

而且，瞧，每次我运行 offlineimap 并尝试在 crontab 中重定向输出时，它都不起作用。下面是我的.offlineimaprc。

[general]
ui = TTY.TTYUI
accounts = Personal, Work
maxsyncaccounts = 3

[Account Personal]
localrepository = Local.Personal
remoterepository = Remote.Personal

[Account Work]
localrepository = Local.Work
remoterepository = Remote.Work

[Repository Local.Personal]
type = Maildir
localfolders = ~/mail/gmail

[Repository Local.Work]
type = Maildir
localfolders = ~/mail/companymail

[Repository Remote.Personal]
type = IMAP
remotehost = imap.gmail.com
remoteuser = username@gmail.com
remotepass = password
ssl = yes
maxconnections = 4 

# Otherwise "deleting" a message will just remove any labels and 
# retain the message in the All Mail folder.
realdelete = no

[Repository Remote.Work]
type = IMAP
remotehost = server.company.tld
remoteuser = username
remotepass = password
ssl = yes
maxconnections = 4 

我已经尝试过TTY.TTYUI，NonInteractive.Quiet并且NonInteractive.Basic有不同的变化。无论是否有重定向，我尝试的 crontab 条目都会导致问题。

$ crontab -l | awk ' { print F "> " $0; print ""; }'
*/5 * * * * offlineimap >> ~/mail/logs/offlineimap.log 2>&1
*/5 * * * * offlineimap

我总是得到同样的该死的错误错误：找不到可用的用户界面！. 我究竟做错了什么！？

Answer 1

如果您使用 6.3+ 版本的离线地图，请指定：

offlineimap -u quiet

我知道 OP 指定的 6.2 版，但是搜索 ServerFault 并遇到上述答案的人可能不知道 ui 标志已更改。

Answer 2

使用 -u 开关指定正确的 UI

offlineimap -u Noninteractive.Quiet # right
offlineimap -u NonInteractive.Quiet # WRONG!
