[OpenAFS-devel] Mail delivery (With maildir) to openafs spool

[Hamish Marson]

Hi all.

I've asked this question on the postfix mailing list (And been knocked 
back a bit :), but thought I'd ask here anyway, since things appear to 
be inconclusive so far...

Is anyone curently using AFS volumes as the mail spool for delivering 
email using postfix or does anyone know any reason why it would be a bad 
idea to doit? I've searched the web a fair bit & the closest I've come 
to an answer is Richard Campbells book saying some people are doing it, 
but no details.

I've already discounted mbox as a bad idea & plan to deliver using 
maildir, but I have a choice to make. Do I run multiple servers with 
local filesystems & route to the users destination server using info 
elsewhere (e.g. an LDAP directory), or do I have several AFS servers 
each with a portion of the users on them, and distribute the incoming 
email evenly & rely on AFS so that each server has equal access to each 
users spool area...

Mail pickup by users would be via imapd or pop3 only... No interactive 
accounts.

I've already discounted NFS (Although it appears to be the postfix 
developers favourite) because I just don't trust it (Security wise, 
although I accept I could jump through lots of hoops to secure it with 
private VLAN's etc).

I already know about problems with re-authing the delivery agent as 
well... Not sure how I'd get round that yet, I'm not sure I'd consider 
IP ACL's to be tight enough... (Or I could just use NFS :)


TIA

Hamish.
