autocomplete e-mail-address

Occasional Visitor

Good day,
for a long long time I've been looking for this solution...
When I write a mail, I want the mail address to be completed automatically. This has only worked for the last few years if I start the input with the first letters of the mail. But if I start with the domain name, for example, no mail address is ever suggested!
I have never found a solution to this problem and am now trying my luck here in this forum. I would be very happy if someone could help me!

Best Regards

I believe this is by design, the feature only works for the "user" part of the address, not the domain.

1. debunk2 ( is entirely free to use for anyone.
2. NK2Edit ( is accessible for free only in cases of non-commercial usage.
3. NK2View ( Freeware.
