Re: recipient address is alias

[Winfried Kaindl]

Dear Cassandra,

thank you for the code. This modification works for spamd-2.53, and it
solves part of my problem. If a mail is sent to one single user,
everything works very well. 

But if the mail is sent to an alias that represents a list of users, the
mail is not scanned by spamd. Because starting spamd with Option -u root
does not work. 

Regards,

Winfried
