Sounds like pretty standard spam-or-phishing - but THIS one was really close to the original. The mail contained none of the spam-typical typos or grammatical mistakes - the wording was copied exactly from the T-Com originals. I became even more curious now and compared it bytewise to one of the original monthly T-Com mails - only to discover that only
- My T-Com account number,
- my wife's name in the mail header (we both are listed at T-Com as account holders) and
- the mail was adressed to my web.de address - not the one listed with T-Com .
Dear me - those spammers really get better...
