how do you come to the conclusion that it matters how busy "this server
is"? jesus christ you are asking *remote servers* for their answers and
the request as well the answer passes different routers, ISP's and
likely a *chain of forwarders* until you don't recursion at your own and
even if you do you have no control how overloaded one of the networks

Thanks for your comments. I understand as DNS uses UDP that there could be some DNS queries which might get lost if the CPU or network is too busy but the thing is that this server is not so busy really. It has 2 cores with 4 GB of RAM and the CPU averages to 2% usage. The network averages to 1 Mbit/s traffic and there are around 600-700 processes running for 1100 mailboxes. Note here that this

SIP auth failed "wrong pw" but pw is correct
Hi

the client in a realtime DB, our client has us configured as a friend and
also has a register => username:password@our.host/username line in his
sip.conf.
When he starts his system he gets an auth failed log line and we get:

Thanks Joseph, Aki, but something missing from upgrade document, where

Nice to get to hear this. However, the password is not stored in clear text

Indexing Mail faster
Hey Joseph
Thanks. Strace seems like a very useful tool
Only problem is that I dont think it is maintained on ubuntu.
Tried to run:-
apt-get install strace but could not download it.
Might need to download and build it. Do you know any other way of getting
it?
Thanks

Certificate cache on iOS with sending mail
I deleted the certificate already, but I think it only uses that for imap/dovecot. I don't think it actually stores one for smtps (or am I not talking sense here).
