Where in the address is the apostrophe? If it is in the local part (left
of the @), all recent versions of Mailman should be accepting it. If it
is in the domain, it is not a valid domain name.
If the apostrophe is in the local part, and mailman is calling it
hostile, perhaps it is being entered as a right or left single quote
instead of an apostrophe. If not, what Mailman version is it?
If the apostrophe is in the domain, the address is not RFC 821/2821/5321
compliant and is probably not actually deliverable.
The actual characters which are (dis)allowed are defined by (from
Mailman/Utils.py)
_badchars = re.compile(r'[][()<>|:;^,\\"\000-\037\177-\377]')
# Strictly speaking, some of the above are allowed in quoted local
parts, but
# this can open the door to certain web exploits so we don't allow them.
# Only characters allowed in domain parts.
_valid_domain = re.compile('[-a-z0-9]', re.IGNORECASE)
