- For several years, I have run small networks with /var/spool/mail
- NFS-mounted from a single server to a bunch of workstations. I have
- yet to have a problem doing this. Most of these machines have been
- Sun's running a recent version of SunOS.
-
- However, as I understand it, due to various bugs in various vendors'
- rpc.lockds, this is running the risk of getting one's mailbox
- thoroughly hosed if more than one process tries to write the mailbox
- at once.
-
- I am now working with a network of Sun SPARC's running SunOS 4.1.2 as
- well a few DECstations runing Ultrix 4.2a. We are using IDA Sendmail
- 5.65c.
-
- I'd be curious to know how many folks have actually had this kind of
- problem -- if it turns out to be very few, NFS seems like it would be
- worth the convenience. Specific experience about the reliability of
- the SunOS and Ultrix lockd's would also be interesting.
-
- Also, where do the Elm lockfiles fit into all this? Would they
- prevent this problem (if everyone were to use Elm, that is), or do
- they merely keep multiple copies of Elm from manipulating the same
- mailbox simultaneously.
-
- All discussion, thoughts, and email are welcome...
