The following is the specifications of our server: HP Prolient 380 G5, Xeon E5335 2.0 GH, 4 GB, windows 2003, exchange 2007, 80 mailboxes with 2gb average size. The server is connected
through 1mbps internet link. the server shows very less cpu load (1 - 2 %), the page file (currently 6GB) is almost totally in use, free physical memory is less than 100mb
The problem is that some emails won't reach the designated mailbox or will take a long time to reach. I sent an email (external) with an 4mb attachment to an exchange mailbox. from the message tracking results, it's very clear that this particular email generated two entries with RECEIVE and DELIVER eventIDs, nevertheless I didn't receive it through outlook.  Sometimes, there won't be any trace of an email message in the smptReceive log, even though sending party would confirm that he already sent it

maybe you have spambot on system

run combofix and hijackthis

also you can use wireshark (filter only smtp port 25) to check what is going on

there could be many reason

1)your public IP is in blacklist

please check @ http://www.mxtoolbox.com

2) your PTR doest not exist in ISP

reqest your ISP to create mail.yourdomain.com PTR and assiciate with your pubic ip.

3) you have good internet line but not sufficent bandwidth availible for exchange to upload email in global cloud.
restrict user for any upload.

4) RBL is enable on remote end and you are list in the list

hi, itubuf
1) the ip is not blacklisted
2) a ptr record is already there
3) upload is irrelevant as the problem is with received email
4) again this problem is related with received email

GhouseAdmin, I tried with reputed web emali services such as hotmail and google, spf record is not the culprit.  After restarting the server,  memory page usage was about 2.8 GB, and the server seems to be working fine, nonetheless it will hjke again to 5.8 GB, and will not go down, is this normal? is memory upgrade is required in this case?

1. are you using ntfs or fat32 - maybe convert to ntfs
2. run defraggler on system  http://www.piriform.com/defraggler
3. switch of page file in system - (or leave it very small) - check what will happen

There is around 100 GB free space in the volume containing mailboxes database
I am planning for 4 gb memory upgrade making a total  of 8 GB.  I hope this will solve the problem
