This is how spammers learn your address. They don't spam me that much. Remove your mail address from your signature. We already know it from looking at the headers. If you must put it on the signature, defang it.
Way off-topic here, but spammers will learn of your address from many, many places. Some will also be picked up from email archives, but Matthias adding his address to his signature or you not doing so, makes zero difference. Obscuring might make a slight difference, but I doubt it.
The people who receive the most spam are the ones with the most private (non-business) contacts.
Also, no matter how well you guard your mail address, as soon as you tell it to someone else it's out of your hands. I suspect a good chunk of addresses nowadays is harvested by shady apps from people's address books on their phones.
Those tools do not have access to the mail addresses I use on mail lists, and the bad guys still have them. One of the known harvesting method was traversing websites with robots searching for strings that seem to be addresses - a mail web archive or a forum is an excellent site for doing so. -- Cheers / Saludos, Carlos E.
