Thank you Phil you have been very helpful!

So if they are now linked through MailScanner, does it mean you cannot Yum
Update?

How do you know if you have the correct Perl modules?

 

Of all the articles and forums I searched, I never came across anything
mentioning this caveat.

Would it be ok to install DCC, Razor and Pyzor after I have installed
MailScanner?

Hazel O'Connor wrote a song called "If Only!" which comes to mind. 

 

I spent all day yesterday installing ClamAV, Spamassassin, and then
MailScanner. God did it take some time and consideration! Days spent
researching over the net only to give myself a headache and every bit of
information different. I Had looked at MailScanner because it was mentioned
so much in the forums. Oh well at least I can say I have learnt something
this weekend.

"If only" I had waited and seen this reply! I am now wondering if I should
just reformat and start again!

True, so true! But a shame on society that we need it.

 

So now I will go away into the corner and sulk!
