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

我尝试过不同变化的TTY.TTYUI,NonInteractive.Quiet和NonInteractive.Basic.无论有没有重定向,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

我总是得到同样该死的错误错误：没有找到可用的UI！我究竟做错了什么！？
