Of course not, 10K characters is a ridiculously generous number. The idea of setting it to 256 is to catch spammers who send tons of recipients in the to: or cc: line, as you know well. Tell your client he looks like a spammer and got treated like one. he could send half in the to: and the other half in the cc:, everybody would see everybody's name.
