Re: [mailop] Message Store on NFS in a high available setup

[Rolf E. Sonneveld]

Hi, Luis, William, Steve, Noel, Kurt, Andris and all others who 
responded off-list,


many thanks for answering my mail. Apologies for my late reply, I've 
been quite busy trying to pinpoint a mail server/storage problem, see below.


Steve wrote:


In this situation NFS is more of a delivery method than anything to do with 
high availability, as it has no requirement to do any more than share a single 
copy of the data.

Maybe a clustered file system - glusterfs for example - is what you're looking 
for.


Correct, I used the term 'NFS' but what I meant to say was NFS to access 
the message store, where the backend for this message store has a HA 
architecture.

We are huge GlusterFS fans. It is easy to setup, trivial to admin and 
very reliable if you don't get too fancy. Biggest issue is 'growing' 
it as you have to be precise in how you add additional bricks.


However, historically the small-file performance on Gluster has not 
been very good, though they are working on it.


Thus a Maildir based system would not (yet) be a good fit on Gluster, 
especially with lots of customers who leave tens of thousands of 
individual messages in a particular Folder.


Other OpenSource 'white box' HA options are

1) Ceph
2) MooseFS/LizardFS
3) A big NFS server with DRBD as a failover.

Each of those would have its challenges as you get into the millions 
of busy accounts stage, but there are work arounds for each.


The mail server for which I was looking for this storage solution has a 
maildir based format. Actually, we used GlusterFS with the FUSE client 
but got some serious problems with GlusterFS, where index files (and 
some other files) got lost due to some problem in GFS. Redhat claimed 
there was 'some client process' removing these files. But we were able 
to reproduce the problem in a test environment and we could demonstrate 
that the problem was solved, when replacing the FUSE client with the 
plain vanilla NFS client that comes with Redhat (against the NFS 
interface of GFS). However, GFS does not provide a HA NFS solution 
without Ganesha and we didn't like to build another layer of complexity 
on top of GFS to solve the problems in GFS. Hence my question on this 
list. Redhat warned us that GFS is not ideal for handling lots of small 
files (where they mentioned everything under 1 Mbyte as being small), 
but we had to use GFS as that was the only HA shared storage service 
available at this customer; no NAS was present nor any intention to 
purchase a NAS for this purpose. But things may change now.

FFS, do NOT use virtual machines :)


I think I fully agree with you :-) but as I need figures and facts I'd 
like to ask you: can you elaborate on why not? Of course physical 
hardware has major advantages re. speed etc., but as everything these 
days get virtualized, virtualizing shared storage (as we did with GFS) 
has it's advantages too (scaling, provisioning etc.)

I don't believe there's a way to check whether you're blacklisted, but 
if you can get mail through to them (e.g. from another network), 
 are responsive and helpful.  That's my 
experience at least.


They may even be lurking on this list and helping you as I write this?

Hi,

My experience with BT is that you will need to have SPF records set up
for the sender domain if you want to deliver somewhat reliably to BT.

For domains without SPF you can get deferred with the message:

421 Too many messages (1.5.7.2) on 2017/10/03 13:39:53 BST from
un-validated IP address: INSERT-IP-HERE Please add a SPF record for the
domain INSERT-DOMAIN-HERE to your DNS or ask your Broadband Provider /
Domain Registrar to do this, we will be unable to deliver email until
this is done due to the volume of email being sent from this IP address.
Guide for bulk senders www.bt.com/bulksender

I suspect this does not solely depend on volume but also on IP
reputation (internal to BT, not any RBL) as I've had this happen for
only some of the IPs in a cluster where all IPs have been delivering
similar volumes towards BT accounts and none are listen in RBLs.

Hi,

Does anyone have a list of the web/mail client support of the
List-Unsubscribe header? The list-unsubscribe.com site does not seem to
have it.

*Free mail addresses & web interface:*
Live.com/Office365 -- only support the mailto
Gmail  -- supports the first listed method
Yahoo -- does not support it (? did not seem to work with mail that had
header)
Fastmail
GMX
AOL
Proton
Zoho
Yandex
ICloud

*OSS/Free web interfaces *
Dovecot
...

*Mail clients*
Outlook
Thunderbird  -- requires plugin to support it
Apple iOS -- supports it
...

Any remarks on this are appreciated. Thanks,


David
