Hi,

-------------------------------------------------------------------------

***Sometime it connects and sometimes not.***
My exim is running on machine which has
-------------------------------------------------------------------------
# free -m
              total       used       free     shared    buffers     cached
Mem:            60         57          2          0         13         24
-/+ buffers/cache:         19         41
Swap:          255          0        255
[root@exim-2 spool]#


-------------------------------------------------------------------------
Even i'm not getting mails from REMOTE mailserver.So i logged onto
mailserver itself and did
exim -bh <ip>

Its shows that mails are accepted!!!
<<PLEASE SEE ATTAHCED FILE EXIM.TXT>>

On mailserver itself if i try to do test for local user i see:
----------------------------------
# exim -bt dilipm
dilipm@???
router = localuser, transport = local_delivery
-----------------------------------------------
But when i try to send mail from REMOTE mailserver i get a bouce saying
