Question about mail server

Question about mail server

[Tony Gogoi]

Hello,

What can be possible reasons for which a mail client (Outlook Express)
does not retrieve mail from the Linux mail server ?

I created a user account "mtwain" on a mail server. Any mail sent to this
account gets appended to /var/spool/mail/mtwain which means messages
correctly enter mtwain's mailbox (on the server).

However, outlook express is not able to retrieve mails from
/var/spool/mail of the linux server. All it displays are "no new messages"
each time even though the account on Outlook express has been set to POP3
and mtwain and /var/spool/mail/mtwain still has messages in it.

/var/spool/mail of the mail server resides on an NFS server which is
correctly mounted as one can view the contents of /var/spool/mail from the
email server.

This problem is for any new user account only. And there are no problems
for mtwain to send mail as well.


Thanks,
Tony

The user can read /var/spool/mail/user?

Yes, on executing
su - mtwain
ls -l /var/spool/mail shows -rw------

Was there any modifications that was done to the file?  Certain characters
are sued to mark read and unread messages and ones set for download.  If any
of the characters are messed up, it will assume there are no messages to
download.

If you connect to the server from a telnet session using the mtwain
account can you see that the mailbox has messages in it? Use the "top"
command from within the telnet session to view the message body.

Re: Question about mail server

[Tony Gogoi]

I haven't connected to the server using telnet due to extremely strict
firewall settings on that. However it appears there is more than meets the
eye.


The setting actually is

				|
                            	|
			Foundary Switch (performs load balancing)
				|
			      |   |
                            |	    |
      			 |	        |
                 [Mail-Server 1]       [Mail Server 2]

There is also an NFS server on which /var/spool/mail is stored. So, mail
is not physically stored in the mail servers.

Mail server-1 is the primary mail server.

Mail server 2 has RAID-1. One of its hard disks was replaced last week.
Since then it intermittenly generates "disk at (0,0,1,0) returned SCSI
status:2 ...." and "disk at (0,0,1,0) returned request sense at ..... Non
recoverable error".

When Mail server 2 is turned off everthing's fine. When mail server 2 is
turned on, only the newly created user account (after replacement of HD)
"mtwain" fails to receive messages, though it can send messages. Outlook
express does not return error though.

And the interesting thing is, even though Mail server 2 is turned on,
POP-3 exchanges take place bewteen Mail server 1 and the host machine. And
yet, the outlook express on the host machine does not retrieve messages
for account "mtwain" which it does successfully when mail server 2 is
turned off.

I get the feeling that the RAID-1 disk which generates intermittent
"error" messages is the cause but don't know why.

Thanks,
Tony

Maybe the account is on both servers, but the data is only being stored on
one?

Re: Question about mail server

[Tony Gogoi]

Yes, the account is on both servers, but /var/spool/mail is on the NFS
server not on any mail server.

Bad sectors that come and go

[Darío Mariani]

Hello:
   I have a dual xeon server with an Adaptec 29320 and a Seagate Cheetah 
UW320 SCSI. I do the following:

1) I install RedHat 9.0 (also tried Fedora and SuSe 9.0)
2) I run badblocks, no bad sectors reported.
3) I run stress (http://weather.ou.edu/~apw/projects/stress/) for a while.
4) I run badblocks again, now there are bad sectors reported.

   If I repeat these steps, I get the same results (with different 
sectors reported as bad). I think that the problem is the SCSI driver 
but I'm clueless, so can anyne give me some hints on where the problem is?
   We had the same problem with an IBM disk (same characteristics), with 
the diference that RH 9.0 hanged when installing.
   Thanks,
		Darío
