The switch-case in src/imap.c contains lots of translatable strings, each case contains _("IMAP error on %s:") and then the error messages starting the string with a space, like _(" connection refused\n") Why not put that space into the end of the "IMAP error on %s: " string, instead of on each error message string. This would make it one place where one can miss the space, instead of lots and lots.
