Invalid email address (recipient)

Invalid email address (recipient)

Hi,

I'm looking to use Zoho Mail with my domain as a replacement for Fastmail.

Yesterday, I attempted to sign-up to a Perl discussion group, but the confirmation email address is classed as "Invalid" by Zoho Mail. The mail address is:

beginners-sc.1270513331.hjpfahpeapbopmaejkmf-mail=mydomain.com@perl.org

I'm guessing it is the "=" symbol that is causing the problem. However, it would be great if this could be fixed, since there a number of groups I am a member of that use this kind of address for confirming membership.

Cheers,
Richard
