How to calculate mail storage/traffic used on Linux server?

+3 votes
296 views

We have to setup a server which gets a copy of all messages send and received by our mailserver as a 1:1 copy. Mails send to multiple recipients should be calculated and saved per user. (great if you usually have lost of mails send to groups of people.)

So no duplication should be used here. (e.g. save the message and refer the different recipients to it.)

How can I calculate the current traffic in the best way to extrapolate the amount of space to be planed for the new server?

Outbound traffic spike every 30 minutes on my Linux server?

Since last two days one of my CentOS servers has been generating a small spike of outbound traffic every 30 minutes (X:00 and X:30). It's not enough traffic to really cause any notice except for the fact that it is a very regular pattern and it started abruptly at midnight Sunday.

I tried grepping through my firewall logs, but have been unable to find anything useful there either. I don't see any cron jobs that would generate network traffic. Any suggestions how I can go about tracking this down?

Any ideas on updating contact pictures in mac mail using a plugin?

Mac mail uses the contact pictures to display senders image. I would like to write a plugin to fetch a picture based on senders email.

There is plugin called Face2Face that does pretty much this using Facebook, gravatar... but it doesn't let you specify a custom URL or image source.

LTE: How does up-link traffic flow template work at UE side ?

I am not sure whether my understanding is correct or not. As per my knowledge, UL-TFT at UE side takes care of IP packet to bearer mapping. I have seen many reference of LTE UE stack for user plane and found IP layer is just above the PDCP layer.
Packet filters are communicated to UE from the network using NAS signalling.
I just want to know where exactly/which layer is responsible to do bearer mapping at UE side.
