in front of citations, I get this message:

Often, I want this to be in english, and with english date format (because the mail will be read by people who don't understand german).

But it seems, I can't change this (according to an IRC answer):

<sebastian> How do you change the language of the text that's inserted by evolution before citations to english?
<andre> you cannot, it refers to the language that you use the User Interface in

It would be ok to change this permanently. Most german speaking people I send mails to will understand english messages, too.

Actually, in private mails (which go to german receivers), I wont need this message at all, so I can simply delete it. But for replies to mailing lists, I need the english message.

It would be even better if I could configure evolution to generate _two_ lines (an english and a german one) so I could delete the one I don't want.

regards,
Sebastian
