I am using Webmin 1.860 (Virtualmin 6.01) under CentOS Linux 7.4.1708 with postfix as a mail server. I performed some experiments with MIMEDefang (installation from EPEL) and then I removed it. It is not present within any config file.
However, when I try to check Virtuemart's configuration, I get "The MIMEdefang mail filter can only be used with Sendmail" and the script stops without any further checking.
I cannot find any reference to MIMEdefang anywhere within the system and I could not find anywhere what the configuration script checks and locates it.
Can anyone help regarding this issue, that is overcome this MIMEDefang checking error?
