How big is your email server?
| Posted by Tomcatf14, 11-27-2007, 11:12 PM |
| Anybody has experience running qmail or exim beyond 8TB of data? Any performance issue? One of my client would need to archive their emails for a decade...so the data storage would be the main issue here. I have never run such huge email server before...any input?

| Yea....what is the biggest supported file size in Qmail + Squirrelmail?
|
| Posted by activelobby4u, 11-28-2007, 11:57 AM |
| There's a file called /var/qmail/control/databytes which controls the maximum size of a message qmail will send. By default, this file contains a "0", which means there is no maximum.

| Thanks for that...but my question is more towards the entire mail system. Any limitation for support up to maybe 10TB of emails on the system? My client need to archive many yrs of emails so the size will grow. They would need to be able to store it within their webmail interface or through IMAP folders.

| Do you mean 10TB of email DATA being sent? Such as attachments?
Can you clarify what exactly you mean, for the email QUEUE itself to be 10tb without any attachments I do not even want to imagine the size of the email database but you can be safe to say it will be 100% spam as it would be way greater than the millions.
Are they sending attachments? If so you would be better sending the email without it and linking to the attachment to avoid the overheads of the MTA.

| I would suggest you to look for enterprise mail servers such as exchange to attain the results. Qmail/exim has its own limitations over handling huge incoming and outgoing mails.
However if is just about displaying/storing email data, any webmail client would be enough, as after all they just display the file in the backend through their interface and authentication is based on php/mysql for most of the webmail clients.

| Not incoming/outgoing for 10TB. But the space will be used for archiving. To store the old emails in the webmail folder. Like "Year 2000", "Year 2001".....and etc.

| In that case any reliable webmail client can be used . May be horde openwebmail or squirrelmail would suit your needs

| How many TB can Unix/Linux support on a single volume?

| What you need to worry about isn't QMail/Exim etc, but your IMAP/POP server.
As for the filesystem limit, that depends on the filesystem you're using. You may find the following Wikipedia article useful:
http://en.wikipedia.org/wiki/Compari...systems#Limits
Of course, depending on the nature of your IMAP server you may be able to make your mail spool consist of multiple filesystems, each under the limit for that filesystem type.
(And, of course, you have already planned the backup and recovery for this volume of data )
