named and dovecot problem.... errors in messages - log

[ATT1]

Hello,
I am getting a lot of perhaps needless errors in the /var/log/messages. First, dovecot complains he has no write permission? (I never changed anything) ; second, NAMED complains that it cannot allow some Voip-phones on 192.168.100.* to get the proper DNS stuff... (?)

Here is a quote from the messages log:

Aug 27 00:35:28 srv01 postfix/pipe[73920]: 97391258087B: to=<bg@local.lan>, relay=dovecot, delay=0.09, dela

Aug 27 00:35:28 srv01 postfix/qmgr[4685]: 97391258087B: removed   ; -> so does that mean the mail is getting lost ?
