Can anyone shed some light on how email addresses in my address books get corrupted?
I recently had to email the same note to an ex army group, most of whom I rarely email, and found almost a dozen came back delivery failure, on checking them agaist those in my data base I found most of them were unchanged but a few had an aadditional letter tagged onto the end, i.e. another@talktalk.netm where the 'm' came from I have no idea, can anyone help, and can it be prevented?
Regars to all.
