+     * When the buffer fills up, fixed Sendmail versions remove comments etc.

+     * Postfix removes comments etc. only when the amount of non-address text
+     * in an address expression (text separated by commas) exceeds 250 bytes.

+     * With Sendmail, the address part of an address expression is the

+     * non-comment string; that string is the address part of the address
+     * expression, so there is no ambiguity.

+     * Finally, we note that stress testing shows that other code in Sendmail
+     * 8.12.8 bluntly truncates ``text <address>'' to 256 bytes even when
+     * this means chopping the <address> somewhere in the middle. This is a
+     * loss of control that we're not entirely comfortable with. However,
