Add external email to Mailing List

[dgmufasa]

Hello all,

How would one go about adding an external email account to a mailing list (using ISPConfig 3 and the SOAP interface)?

I saw the functions like:
mail_mailinglist_add
mail_mailinglist_delete
mail_mailinglist_update
mail_mailinglist_get

but it looks as though the "add" is designed to add a brand new email to the mailing list (hosted with ISPConfig). What is desired is to add emails from gmail, hotmail, etc. to the mailing list.

How can this be done - or - am I missing something?

TIA
