Inbound Mail Rejected Due to Mail File Limit

Hi I'm having an issue on my Domino 6.5.6  on Windows server where sometimes email will be rejected due to insufficient space in the user's mail file.  We don't set any limits on mail files & the user has nowhere near the file usage that others have.

Here is the exact error message:

"Your message is larger than the destination computer is willing to accept, so it was returned.  The error message below indicates the size of your message and the maximum size allowed by the receiving E-mail system.  You may be able to split your message into several smaller pieces and have them delivered sparately.

Your message wase rejected by smtp.mydomain.com for the following reason:
   Requested mail action aborted: exceeded stroage allocation
The following recipients did not receive this message:
  <firstname.lastname@mydomain.com>"

After I restarted the ROUTER task the email came through fine.  There are no restrictions for mail size or email database size on our Domino server (I know probably foolish).  

Does anyone have an Idea what would cause this?  We have a firewall that strips off some ESMTP keywords but if that's the source why would resarting the router task fix the issue?

Thanks in advance Wade

I don't think this is an issue with your mail proxy as you told. IT seesm that somehow Domino starts to be more restrictive.

Did you  check the database size of the box files, user mail filex causing the error ? As you know there's a 2 GB filesize limit in domino. May be some databases are close to the maximum size and this is causeing error. In that case when you start router may be some servertast starts to compact the databaes especially the .box files.

Please check all the realted file sizes.

Actually Domino 6 and newer no longer have any file size restrictions ( Just OS restrictions )

What about any anti-virus or SPAM filters ?

Anything running on the Domino server besides the Domino tasks ?

I hope this helps !

Thanks SysExpert,

We have a couple things that might have interfered but most likely it's our AV scanner.  We're using Sophos Puremessage and it interfaces somehow with the router & mail.box.  That could be the ticket.  We also use SpamJam as an anti-spam solution but it doesn't act until the mail is being delivered, so I don't think that is the problem.  

Does anyone have any knowledge as to whether Sophos could cause this issue?

Yeah 32-Bit systems are restrictive on file size. Hence the size limit I talk of. Your problem here is your SMTP server says it can not store the mail since the user database in question is not capable of accommodating or able to allocate more space.

If the problem were "Mail size exceeded" then we would have to check on A/V or SPAM eavaluating mail boxes.

As far as I see this could be the database size. I'll suggest you monitor all mail databases under your server's mail folder.

I have seen similar issues with Symantec AV for Domino, when it can not open an attachment, or it exceeds the limits set in the AV setup for maximum expanded attachment size.

Yes but in this case how come it would be solved after restarting the router ?  As you know Domino AV agent runs as a separate tast and independent of mail task restarts. So the only think I can think of is some .box or .nsf mailbox getting compacted after smtp restart.

Have forwarded the issue to our AV vendor tech support department.  I believe this is likely the issue & will confirm or deny my suspicions in a couple days.

Thanks,

jameswayit ,,,  Could we please analyze the case to know where the problem is ,,,
we have mentioned above (my Domino 6.5.6  on Windows server where sometimes email will be rejected due to insufficient space in the user's mail file)
And lets ask our selfs some questions :

1- Does this problem happen with the same recepient users everytime or it happens with different ones each time ???
2- Does this problem happen with the same sender  everytime even if he sends it to a different recepient each time ????
3- Try to send the same message to the same intended recepient through a free emails account e.g. Yahoo, Hotmail etc.
4- The First level of checking in bound messages  is the security level and mainly the Anti- SPAM and then if it passes  it will be checked by the Ant-Virus then if it passes it will go to the Domino server( which has no restrictions and no rules ) . Hence you better check  both the Anti-SPAM and the Anti -virus configurations and settings .

Finally, you have mentioned above that you are using the Sophos puremessage as an AV and for sure it is running as a task ( on the Server console sun the following command " Sh task"  and you should see the AV agent list over there . So what I thing and I am not sure about when you restart the " ROUTER" using ( res task router) the AV task could be initalizing when message passed through and delivered to the recepient

Hopefully this is Helpfull

Hi

Here are your answers:
1- The recipient has always been the same person.  There is a lot of email betwen the two
2- The sender for all the known cases has been the same.  They use a large internet company to host their email & the sending server appeared to be different from the Domino log of transactions of when the message succeeded & when it failed.
3- Have not tried to copy & send the same email from a different source - When it happens I will try that .
4- Our SPAM filter activates well after the message has been received by the server during the delivery process to the person's email file so I am sure that it is not that.  However, Puremessage modifies the MAIL.BOX template & could easily be causing this issue.  

The point about the AV being in flux is a good one but I don't think it is the case because the sender did not re-send the email until about 20 minutes after I had restarted the router task.

Hi

What I can say for now is please check the following similar cases on the net .. in fact , most of them refer to either the AV or sometimes a SPAM case or an illgal attachements etc.

Hopefully this is Helpfull

I contacted our AV vendor & he pointed me to possible issues with our NAB.  Here is the response from Sophos bellow.

"I think that this is more likely a Domino issue than a PureMessage issue. Please see the following post which details how to attempt to resolve the issue:

http://www-10.lotus.com/ldd/nd6forum.nsf/869c7412fe5d56b7852569fa007826e3/c9544e93eded2a6b85256f89007fdd68?OpenDocument

If this does not resolve the issue please would you see if disabling PureMessage then resolves the issue?

So,,,

According to what is instructed in the  link sent by the AV vendor may I recommend the following  to be run on the " Sever Console" for the mailbox of the user who is having this problem :

load fixup -f mail\( the mailbox of the user who is having the problem )
load updall -r mail\( the mailbox of the user who is having the problem )
load compact -c - i mail\( the mailbox of the user who is having the problem )

And if this doesn't work do what he recommended by disabling PureMessage but becarefull because this is risky ,,,, try to disable it for some time (2-3minutes ) and let the sender resend the same email again and check if this works . you may also try the same thing with the AntiSpam but again I am saying the same thing this is risky so dont keep any of them disabled for long time .


Good Luck
