    Default amivisd - Subject: ***UNCHECKED***

    I've been running some more tests (sending about 1msg per 1 or 2 seconds) and have been seeing the occasional :

    Code:
    Subject: ***UNCHECKED***
    
    WARNING: possible mail bomb, NOT CHECKED FOR VIRUSES:
      Maximum number of files (1500) exceeded at /opt/zimbra/amavisd/sbin/amavisd line 5042.
    I can see that I can increase the open files limit - but should I really be hitting it with sending mail to 5 test users like this? Is there a more recommended level for a zimbra install?

    My ulimits are currently the CentOS4.2 defaults :
    Code:
    ulimit -a
    core file size          (blocks, -c) 0
    data seg size           (kbytes, -d) unlimited

    I'm sending some mails with tar.gz files - but most have no attachments. Not in a VM.

    From about 100 to about 4000.

    Default archive

    This 1500, btw, isn't a file system limit - there's a config item in amavis (don't check archives of > X files). That's what you're hitting, I believe (check conf/amavisd.conf.in for the value)

    I've upped that to 5500. I may skip scanning on tar.gz files altogether as it looks like it'll be quite a load given how many of them we see relative to the virus risk (currently!).

    hi billy

    How did you up the limit to 5500?
    What is the command?
    There isn't anything in the Zimbra console admin to do this.

    Thank you

    Okay, I modified the amavisd.conf.in file.
