Questions tagged [spam]

DO NOT USE THIS TAG ON QUESTIONS THAT ARE SPAM, we have a special flag for that! Questions about bypassing somebody else's spam filter are also not welcome. And keep in mind that this is a programming Q&A site, not a general computer support site. Spam is the use/abuse of electronic messaging systems (e.g. e-mail) to send unsolicited bulk messages indiscriminately.

This tag would be appropriate for programming questions about spam classification, etc.

We do not control the email filters of Gmail, Hotmail, etc. If you want to learn how to bypass them, ask the people who maintain those filters instead (but be very much prepared for "are you serious?" replies, or, most likely, no reply at all).

Understand that spammers read this site and so divulging methods for bypassing somebody's spam filters is comparable to sabotage. Please do not post such solutions.
