If there are any errors appearing in the mini-buffer, move yourself to *scratch* buffer and type:

After the last bracket ")", press C-xC-e. When the error you mentioned arises in this state, you will find various info displayed in *Backtrace* buffer. Please throw these info and the process of the error you ran into to mew-dist@mew.org.

If the error appears while the content of the mail becomes displayed, type:

4.3 Mail apportioned by procmail is unreadable.

(Version 1.70 or lower)

Q.

I divide mail into each folder by using procmail 3.10. When I try to read that mail by means of Mew-1.70, the encoding for that article becames failed. At current, I use C-c C-l to read mail. However, can i read mail without using C-c C-l?

A.

Please try to add the following command in $(HOME)/.emacs.

(setq mew-keyval "^\\([^ \t:]+:?\\)[ \t]*\\(.*\\)$")

4.4 When the amount of mail grows over some number, since then the mail will not be displayed.

Q.

When the amount of mail in a folder grows over some number, since then the mail will not be displayed definitely.

A.

In case of using MH

In scan.form, try to change the number that is bigger than 4 in the first line coming like:

%4(msg)%<(cur)+%| %>\

In case of using IM

As the setting of Form in $(HOME)/.im/Config,

Form=%5n %m%d %-14A %-18S %b

, try to change the number that is bigger than 5 at %5n. Furthermore, when you set %5n as %5l, the outcome of scan might be distorted. But, because of this setting, all digits will be displayed even if they exceeds the specified width( which equals 5 in this case ). That is, Mew becomes not to operate mistakenly anymore. For further info concering Form, please refer to 7.4 I'd like to know the setting of Form in $HOME/.im/Config

4.9 Folder name completion doesn't work.

Q.

Folder name completion doesn't work in a summary mode.

A.

Push 'C-uZ' in a summary mode to update your folder cache file $(HOME)/Mail/.folders. Don't forget to update it if you have just updated your Mew version from 1.70 to 1.9x because its format has changed.

If you have numeric folders like "+foo/199805", put the following setting in your $(HOME)/.emacs.

(setq mew-folder-list-skip-pattern "^\\.\\.?$")
