Searching google I found that this error isn't related to the number of
users in the list, it occurs because the total number of addresses in the
To: and Cc: headers of the post equals or exceeds max_num_recipients. But
in documentation is said that if this option is set to 0 it has no limit.
And my post have only one recipient in To:, the list itself. So what may
be causing this?
