+Hi, Sergei.  I'm not clear on where exactly you are seeing a problem\r
+with this tab in the subject line.  Is it showing up somewhere you think\r
+it shouldn't?\r
+\r
+Headers that are broken across multiple lines must be indented, so I\r
+think it is fairly standard for MUAs to insert either a space or a tab\r
+at that point.\r

+I'm not sure libnotmuch should be doing any scrubbing of the message\r
+contents.  The emacs UI does seem to replace the tab with a space,\r
+though.  Maybe other MUAs should be doing the same?\r
