VMA have made some pretty major changes to our spam filtering system recently – we are now running emails through various systems (like Barracuda, SpamCop & SpamHaus etc) that will facilitate the removal of spam.
To improve the filtering of your domain, ensure spam assasin is enabled & try setting your spam assasin settings to 3 (5 is default) plus you can also enable auto spam training of mails in the spam folder by setting up a cron. Hence, we recommend you move all spam mails to the "Spam" folder via webmail (Roundcube) to allow the spam assassin to learn the pattern and block similar mails as spam.
If you are using the IMAP protocol, this can be also be done directly from Outlook but check to make sure it is going to the correct folder in Webmail.
This will further improve the spam filtering as spam assassin gets to learn the various spam mails that you are receiving.
CRON details:
~~
/usr/local/cpanel/3rdparty/bin/sa-learn -p ~/.spamassassin/user_prefs --spam ~/mail/*/*/.Junk/{cur,new}
~~
with timing setting of:
* 0,12 * * *
This will run twice per day to facilitate the learning process.
