There is something odd about your email. When I look at in mutt I see the patch, but if I save it and try do git am it complains. Looking at the file I see: U2luY2UgUFZIIGd1ZXN0cyBhcmUgdmVyeSBzaW1pbGFyIHRvIEhWTSBndWVzdHMgaW4gdGVybXMg b2YgbWVtb3J5Cm1hbmFnZW1lbnQsIHN0YXJ0IHRoZSBndWVzdCB3aXRoIHRoZSBtYXhpbXVtIG1l bW9yeSBhc3NpZ25lZCBhbmQgbGV0Cml0IGJhbGxvb24gZG93bi4KClNpZ25lZC1vZmYtYnk6IFJv Z2VyIFBhdSBNb25uw6kgPHJvZ2VyLnBhdUBjaXRyaXguY29tPgpDYzogSWFuIEphY2tzb24gPGlh bi5qYWNrc29uQGV1LmNpdHJpeC5jb20+CkNjOiBJYW4gQ2FtcGJlbGwgPGlhbi5jYW1wYmVsbEBj aXRyaXguY29tPgpDYzogTXVrZXNoIFJhdGhvciA8bXVrZXNoLnJhdGhvckBvcmFjbGUuY29tPgot .. and so. Have you changed something recently in your git sendmail setup?
