Greetings,
I have several users reporting that PDF attachments are coming in corrupted. They are using either thunderbird or outlook on windows xp. I have flushed the cache files for the users, but the problem still persists. Could anyone offer some troubleshooting tips?
Thanks in advance for any assistance.
Below is my version and config.
Regards,
Mike

Hi Michael, the chances that dovecot or postfix has something to do with this are nearly null, corruption of spez. file types may result by broken virus scanners , or what i never had expected i had this issue one time on a windows exchange machine with pop3 downloader which had a broken interface bonding, so it was the nic drivers fault, so there may be some equal nic or network problem on the clients side and or virus scanners , proxies etc on their side, a good test is to use some webmail ( i.e squirrelmail ) on the dovecot server itself open some example mails ( which are reported to be broken ) with it and look if they currupted or not, if they arent the problem is on the client side and you dont have to care, if they are allready corrupted on your mailserver check antivirus solution you have installted in the server, disable it for further tests.
