Tárgy: Re: [Exim] Problems with writing to spool

Exim does a set_euid() call to set the id to the user its delivering
mail to when making local deliveries.

Either you need to set the exim group, and make sure /var/spool/mail is
chmog g+w, and is owned by the appropriate group, or leave it at 777,
but also set +t (sticky bit) - this prevents people from deleteing
other peoples mailspools.
