Are you aware that Google Mail does not recognise dots?
This means that if your Google Mail address is myaccount@googlemail.com, then if you change the Reply-To address as my.account@googlemail.com, you would still receive it. It would be the same if you use m.y.a.c.c.o.u.n.t@googlemail.com!
Fancy that…
By the way, when is Google Mail getting out of BETA?
