Postfix giving some odd errors

[fixallthisjunkguy]

Good Morning, I'm using Ubuntu 8.04 which I upgraded from 7.10 and Postfix is the newest version downloaded with apt-get. Postfix is giving me the following error message in the mail.log


mailserver postfix/tlsmgr[22168]: fatal: tls_prng_exch_open: cannot open PRNG exchange file /var/lib/postfix/prng_exch: Permission denied
mailserver postfix/tlsmgr[22155]: warning: process /usr/lib/postfix/tlsmgr pid 22168 exit status 1
mailserver postfix/tlsmgr[22155]: warning: /usr/lib/postfix/tlsmgr: bad command startup -- throttling


ls -la of /var/lib shows:

drw-r--r-- 2 postfix postfix 4096 2008-09-08 16:$2 postfix


ls -la of /var/lib/postfix shows:

-rw-r--r-- 1 postfix 127 1024 2008-09-08 16:42 prng_exch
-rw-------1 ftp 127 8192 smtpd_scache.db
-rw-------1 ftp 127 8192 smtp_scache.db



Does anyone know what the problem might be? I have tried the comments found in one other thread on roughly the same problem. Any help would be appreciated! Thank you very much.

Also here is my main.cf from postfix, just in case someone needed to see it to give me an idea of what to fix.

Ok, I fixed that problem, chmod 700 to all files and the folder /var/lib/postfix then set owners and groups both to postfix user for folder and files.


Now another problem, phew this is getting annoying....

Wow, I'm an idiot, I fixed that too. Reran adduser postfix sasl and it fixed it.....


Now I'm getting

I am able to send emails to users within the domain, haven't tried anyone outside of it, but they do go, but I'm still getting these error messages above. Anyone have any good ideas about them?

[fixallthisjunkguy]

I chmodded 777 to /var/spool/postfix/maildrop and the ownership was set to postfixostdrop and all appears to be working.

This is most likely a temporary fix, but, it works for now. If anyone knows a better work around, please let me know, and hopfully if anyone has these problems in the future, the answers are posted here.
