As I said, it’s an address I created specially for my account and it’s not on any server, only in my local folders in Claws Mail, so it’s difficult to see how it could be accessed there. The address has been used nowhere apart from setting up my user account and even this forum has a different e-mail address for me. I therefore can’t think where it could have leaked from as it simply isn’t stored anywhere else.
I must admit, it’d be rather silly of a cracker who penetrated a security-related database to give that fact away by sending spam to people who are more savvy than the typical PC user and are likely to know where the data came from, but it’s an address only used in one place and the only people I’ve ever given it to is the Let’s Encrypt security team (today). I always take care never to post information of this kind on a forum or public mailing list, for obvious reasons.
Yes, I know it could have been intercepted from a mail server somewhere en routeemphasized text** but somehow I think that’s unlikely as it’s the only address for a very long time at which I’ve started to receive spam.
The possibility of a data breach has to be at least considered, as vigilance is a key aspect of security.
