Patch to add the "=" symbol to the allowed characters. This applies to v 1.27.§

Some email addresses, most notably mailing lists, have a "=" in the email address (Example: zsh-users-sc.1503393158.xxxxxxxxxxxxxxxx-oli=glow.li@zsh.org), but sendmail only allows alphanumeric and "+_-.@".
I have attached a patch that adds the "=" symbol to this list.

Note: this is very similar to my previous issue:
