Hello, I am having problems with Dovecot not sending clients emails bigger then 8-12k (it varies) or attachments bigger then 8-12k. I am also getting 'Corrupted transaction log file' errors ' unexpected end of file while reading header' I have deleted the dovecot.index.log, dovecot.index.cache, and dovecot.index several dozen times.
I started off using Centos 5, with their package of dovecot 1.05, after seeing that there were problems in the package in the http://wiki.dovecot.org/WhyDoesItNotWork, I went with a source install of dovecot 1.09.
Here is my cfg info:

(the login process is 128 because i was experimenting with various numbers (32,64,80,etc)
The /var/log/maillog has hundreds of these: Dec 11 16:27:42 le1 dovecot: POP3(xxx@xxx): Corrupted transaction log file /var/spool/postfix/virtual/xxx.com/xxx@xxx/dovecot.index.log: unexpected end of file while reading header
I turned made it so the mail stays on the server, so i can see that the mail stored there by postfix is the correct size. When email clients download mail through pop3 or pop3s it only downloads 4,8, or 12 k worth of the email (whether it has attachments or not). Here is an example transaction:

To be clear, if i telnet to 110, and manually do a retr on the message it only sends 4,8,or 12k worth of the message. So it does not appear to be a permission problem, it is reading and writing to the directory properly.
The system is x86_64 centos 5, not using the standard dovecot nor postfix rpms that come with the distro. postfix from what I can tell, is working fine, but dovecot isn't. I'm going to try installing cyrus to make sure it's not postfix, but I'd really like to avoid cyrus if possible.
Thanks in advance for any help.
