Accessing email
From Syscore

Hardware / OS
Mail reading services (imap & pop) are currently provided by 5 Sun X4100 Servers, with 4 AMD Opteron cores, running Solaris x86.
These servers run with an AFS cache stored in an in-memory filesystem. We don't use the AFS memcache, as it doesn't seem to like being very large (currently, they are configured with a 1+G in-memory cache.)
Software
Imap & Pop
We're currently running a derivative of UW-IMAP 2002e for IMAP & POP access. There have been quite a handful of modifications to the stock UW code, primarily in support of:
- Our modified maildir mailbox format
- Odd AFS semantics when dealing with UNIX-style mailspools (as we don't support these anymore, these changes can probably be rolled back out)
- Authentication hooks. We could probably use PAM now, but PAM kinda sucks.
- Changes to the path-mapping code to keep people in their "Mail" directories.
- DRAC support
Pine
We also build 'pine' off of this c-client library, and users may use our pine build to read mail on any of our AFS connected systems.

IMAP/POP Server Configuration Tasks
When installing a new IMAP/POP server, be sure to copy the contents of /etc/ssl from another IMAP/POP server so that the appropriate certificates and keys are available. Everything else is happily done by cfengine.
