1. As in Epiphany, there were plenty of duplicate strings identical except for capital letters or a full stop.

2. #:addressbook/gui/contact-list-editor/contact-list-editor.glade.h:6
msgid "Insert email adresses from Adress Book"
(addresses, Address)

3. calendar/gui/apps_evolution_calendar.schemas.in.in.h:31
"Position of the vertical pane, between task list and the task preview pane, 
in pixels."
(between the task list)

4. calendar/gui/apps_evolution_calendar.schemas.in.in.h:43
Time divisions</short> <short>Intervals shown in Day and Work Week views, in 
minutes.
(These tags are deliberate?)

5. designs/read_receipts/read.glade.h:6
"Always send back a read reciept"
(receipt)

6. mail/evolution-mail.schemas.in.in.h:109
"port for starting user runned spamd"
(?? What is this supposed to say?)

7. plugins/default-source/default-source.c:82
"Mark  as default folder"
(repeated without extra space in next string)

8. plugins/shared-folder/properties.glade.h:12
"_Cutomize notification message"
(Customize)

9. shell/apps_evolution_shell.schemas.in.in.h:17
"The style of the window buttons. Can be \"text\", \"icons\", \"both\", 
\"toolbar\". If \"toolbar\" is set, the style of the buutons is determined 
by the GNOME toolbar setting."
(buttons)

10. #:shell/e-shell-importer.c:162
"Evolution checked for settings to import from the following\n"
"applications: Pine, Netscape, Elm, iCalendar. No settings\n"
"that could be imported where found. "
("where found" or "were found"? In the latter case, the sentence is cumbrous, and should probably be:
"No importable settings were found.")

11. #:ui/evolution-message-composer.xml.h:7
"Encrypt this message with your S/MIME Encryption Cetificate"
(Certificate)

Enjoy. :)
