Hello All,

I am struggling to find anything on the interweb,

We have a client and the email address we have been given for one of their employees contains 2 apostrophes.

One of our team is struggling to send an email to said employee. The client says the email is valid, but the postmaster reply tells me otherwise.

could not be delivered. The problem appears to be :
-- Recipient email address is possibly incorrect

Additional information follows :
-- 550 5.1.1 <xx.xx'xxx'[email protected]>... User Unknown

Could anyone shed any light; is this a problem with the user being unknown or is the 2 apostrophes causing an issue.

EDIT: Is there any way to encode an apostrophe?

Cheers
