Apostrophe (single quote) in Forward To address

[andic]

An email address in "Forward To", that includes a single quote (eg david.o'connor@somewhere.com) breaks the creation of a new email account.

Technically any of ! # $ % & ' * + - / = ? ^ _ ` { | should be allowable.

I cannot do anything to change the destination email address.

Anyone know of a solution or workaround for this?

Cheers

Andi
