Before sending a question to the mailing list, check whether it was already asked by using the archives' searchable index. Because not everyone has filespace for me to SEND to. Then put it on a webpage and let those who want it download it. You needn't make it publically available, make a directory like 'privatestuff' touch 'index.html' and put the file in that directory. Tell those who want it where to find it.
Email is the wrong method of sending binaries no matter how man people use it.
