Thanks for the reply shmem. I looked over the docs/man page for pflogsumm and didn't see any feature to split by "from" address or message id so I thought I would just feed it pre-split files.

The reason I need to split these is we provide email list server services to multiple clients and on Lyris they are used to getting smtp reports for their individual lists. So I need to either write a program to parse this info out from scratch or find a third party program to bolt onto Sympa to provide this data.

I suppose I could patch pflogsumm since it is also written in perl but I was wanting to do get this done in a less obtrusive way.

We have a dedicated server running Debian Linux on a T1 line. The hard disk space isn't something my company is worried about me using with this new email server too so that shouldn't be an issue either.

Thanks!
Jason
