Depends what you mean by "outer Greater London". I live in Forest Gate in
Newham and we're E7 and part of outer London on the political definition

(strictly the boroughs that weren't in the Inner London Education
Authority's remit; this mostly matched the old London County Council Area
but part of Newham, namely North Woolwich, was a notable exception). *
Walthamstow is E17. The E post codes go right up to the Greater London
border and even beyond it in one direction, but stops rather short of it
in another.

As a long tern resident of East London I have to disagree with you.
Notwithstandish political definitions, most people regard Forest Gate -
birth place of Dame Anna Neagle and Dame Vera Lynn - as an inner London
suburb.

The difference between formal and colloquial definitions has been behind a
lot of the discussion on this thread and can make it unclear just what area
a person means.

The E post codes do not go to the Greater London border. South Woodford
is E18 but Woodford Green and Woodford Bridge have IG postcodes.

Havering is the eastern-most London borough and none of it has an E
postcode.

True in those directions but E4 goes right up to the boundary and beyond,
taking in Sewardstone, which was the direction I had in mind.
