Subject: Re: Problem with big file in mail spool dir


The error in log file is:

Sep 17 16:59:26 courrier popa3d[15140]: Authentication passed for daigneas
Sep 17 16:59:26 courrier popa3d[15140]: Failed or refused to 
load /var/spool/mail/daigneas

I will get the source and compile to increase the limit at 200 MB /200 K.

Thanks again!
