ot: copy physical mail files ?

[Voytek Eymont]

dumb question warning:

I have two email accounts, me at tld1 and me at tld2
often, get emails intended (by me) for me at tld2 sent to me at tld1

this is purely for my own preferred record keeping preference,

as I run the server, is it 'a really bad things' if I simply copy relevant
mail files from
/var/vmail/vmail1/tld1..../cur to /var/vmail/vmail1/tld2.../cur ?

rather than forward emails as I have been doing?

thanks
