Users can't pop email, I get this error -ERR Maildir invalid (no 'cur' directory)

[mguindon10]

My users can't pop their email. They do recieve mail and are able to get it from webmail but they can't use outlook and such to pop their email. I telneted into the server and tried to login as a user and I get this error.

-ERR Maildir invalid (no 'cur' directory)

Anyone know what this is and how to fix it?

 

[mguindon10]

I figured out the problem just incase anybody else has this error.

Run these scripts:
/scripts/convert2maildir
/scripts/courierup --force
/scripts/eximup --force
/scripts/upcp --force

That converted the maildir over and fixed my popping issues.

Hi all

Revisiting this thread, I get the same type of error:

There was a problem logging onto your mail server. Your Password was rejected. 
Account: 'Mike', Server: 'domain.com', Protocol: POP3, 
Server Response: '-ERR Maildir invalid (no 'cur' directory)', 
Port: 110, Secure(SSL): No, Server Error: 0x800CCC90, 
Error Number: 0x800CCC92

However, I do NOT wish to have my email system switched over to maildir - been there done that and my clients overwhelmingly prefer the simpler mbox format.

New emails get appended to the mbox-style inbox file, but mail clients want to check the maildir-style /cur directory. How can I get these back in sync?

Note - this just started happening after the kernel in my server was upgraded and the server rebooted. I have a trouble ticket in with my hosting company, but I wanted to see if anyone here might be able to shed some light on the issue.

Thanks all-
Mike

Your server's exim might have been upgraded to maildir. Double check if your exim if it is being upgraded and if it is, revert it back to mbox . Check also if you have courier-authlib and courier-imap services running on your server

Hello -

Thanks for the quick reply - where in the exim.conf file do I tell it to use mbox over maildir? Or is that located in another file?

Also, I was told by my hosting company that CPanel apparently doesn't support mbox any longer and permanently uses maildir, which would make sense given my problems. But I do not wish to use maildir and want to stick with mbox if I can.

If that's true about CPanel, then I suspect other people are having (or going to have) issues with their mbox based email system as well....

 

[prodigious]

I think you might have posted in the wrong thread.....we're just talking about email issues here.

 

[tweakservers]

Your host has the options of running the mail in mbox or maildir and the maildir is not a permanent changes by run but Cpanel may probably completely drop mbox in future, there's no final confirmation from them on this at the moment.

 

[prodigious]

Hi,


Thanks again for the quick reply.

I actually run my server / have root access, so I can control all aspects of how mail is delivered.

My main question is - what files should I be editing in cpanel / exim? I checked exim.conf and there was nothing in there that directly said mbox or maildir.

Thanks

 

[tweakservers]

can you run a ps -aux and paste the output here?

 

[tweakservers]

Looks like you are in maildir... try this as root :

service chkservd stop
service courier-authlib stop
service courier-imap stop

Edit the file /var/cpanel/cpanel.config and find the following line ( if it does not exist, add it )

maildir=0

Save the file and run the following:

/scripts/eximup --force
service cpanel restart
service xinetd restart
service chkservd start

You will be back to mbox after this. If you are still having problems, PM me and I will help you to take a look.

 

[prodigious]

Sure -

[prodigious]

THAT WORKED!!!!



Thank you SO much. You have my undying gratitude!

 

[prodigious]

While everything works normally for the most part, I seem to be having timeout issues with the mail server now. DNSReport keeps failing when it checks for it, but when I send mail, it eventually goes through.

Any idea why this might be occuring?

 

[NNNils]

Looks like you are in maildir... try this as root :

service chkservd stop
service courier-authlib stop
service courier-imap stop

Edit the file /var/cpanel/cpanel.config and find the following line ( if it does not exist, add it )

maildir=0

Save the file and run the following:

/scripts/eximup --force
service cpanel restart
service xinetd restart
service chkservd start

You will be back to mbox after this. If you are still having problems, PM me and I will help you to take a look.

After doing this in a server that is already maildir converted, the maildir style folders still exist.
Is it save to delete them? Or is there a back-conversion script?

 

[tweakservers]

it is fine to leave the cur folder on the server as your server's exim is now not in maildir version that will not read into the cur folder.

 

[NNNils]

This solution works fine, however I have 3 servers with same config:

WHM 10.8.0 cPanel 10.9.0-R7965
CentOS 4.4 i686 - WHM X v3.1.0

They somehow every few weeks the problem returns and we need to run the solution above again, although maildir=0 is still in place.
Also at the same time ftp server needs a restart.
In other servers were we applied this patch, we do not need to do this.

This returning of the problems usually seems to occur at the nightly running of upcp scripts etc.

Anyone has an idea?
