Can you tell us if the time these messages started to appear coincided with anything that you did to the system, such as upgrades, installing new software, etc.?
looking in the clamd.log I found a lot of lines like this [ /*/*/*/*.png: Can't parse data ERROR ]
Unfortunately that message doesn't say much about where in the code the error occurs, the function which prints it is just a generic translation of an error code to a text string. If you enable debug logging in clamd and debug messages in libclamav it should tell us a bit more. All you need to do is add the lines LogVerbose yes Debug yes to your clamd.conf and restart clamd. (After the problem is solved, you'll probably want to remove these lines as they can produce a lot of output.)
I added on clamd.conf the next line ExcludePath ^\.png$ But clamd is still sending the error
That works for scanning files in the filesystem, but if you're using clamd via clamav-milter, which I guess is what you're doing as it's a mail server error, I don't think that it will work. It's not an ideal solution anyway.
Is there a way to avoid this ?
It seems best to find out why PNG files are longer handled properly. The debug messages should tell us something.
My config FreeBSD 11.3-RELEASE-p13 qmail (with a lot ot patches) SpamDyke 5.0.1 ClamAV 0.103.0
I wonder if something might be interfering with the mail before clamd sees it. When you get back with more information, could you confirm that you're using clamav-milter and let us see the clamd configuration file? The configuration file is probably called clamd.conf but you'll need to make sure it's the one that your clamd is using. It might help to let us see the clamav-milter configuration too, if that's what you use to feed the messages to clamd. -- 73, Ged. _______________________________________________ clamav-users mailing list clamav-users@lists.clamav.net https://lists.clamav.net/mailman/listinfo/clamav-users Help us build a comprehensive ClamAV guide: https://github.com/vrtadmin/clamav-faq http://www.clamav.net/contact.html#ml
