I know this has been discussed in other threads but I thought it best to start a new one to get some definitive responses for what works correctly with regard to specific needed strings. Apologies in advance for the long post. 

 

I have tested the following with intermittent success in a custom rule with:

Rule Source: Header

Header: Return-Path

Rule Type: Regular Expression

Weight: 999

Rule Text: 

.+\.academy>$
.+\.accountants>$
.+\.actor>$
.+\.agency>$

... and so on.

 

I created a similar rule looking for a specific string in the header for the 'sender name' such as:

((?i)cialis)$
((?i)seduce)$
((?i)nugenix)$

 

The header in the email general would be something like:

Return-Path: <nugenix-for-health-myname=mydomain.com@regex-for-idiots.com> for example. The domain always changes but the sender name almost always starts with or contains the same word(s).

 

 

I know the syntax above doesn't work. It is only one variation I had tried of just about every format I've been able to find either here in the community or in numerous articles and discussions elsewhere. I was pretty convinced that standard regex strings were not being processed properly in SmarterMail. I tried:

nugenix$

/nugenix/i$

(?i)nugenix$

((?i)nugenix)$

^nugenix/i$

^nugenix/ig$

...and just about every other combination I could think of and nothing worked until this one:

 

(?i)(\W|^)(viagra|cialis|medical|seduce|nugenix)(\W|$)

 

I haven't tested a single word or any modifiers like v[i1l]agra yet but I believe this would work as well:

 

(?i)(\W|^)(v[i!1][a@]gr[a@])(\W|$)

 

Maybe someone a little more savvy with Regex could add some thoughts here. My concern with the above working syntax is that 'medical' would probably score john.smith@somemedicalcenter.org a 999 in this implementation. I assume that I need to modify it to include the leading < to make sure it is part of the regex such as:

 

(?i)(\W|^)(<v[i!1][a@]gr[a@]|<cialis|<medical|<seduce|<nugenix)(\W|$)

 

...but of course that will only catch the sendername if it immediately follows the "Return-Path: <" such as:

 

Return-Path: <nugenix-for-health-john=mydomain.com@dating-for-openminded.com> 

 

I was hoping to score ANY location of nugenix in the sendername (not domain) for example even if it is: 

 

Return-Path: <get-some-nugenix-for-health but not: 

 

<dr.johnson@nugenix.bigpharma.com> 

 

 

What I need is a regex that will catch <anycharacters+cialis+anyothercharacters+@  but being a regex imbecile I'm not sure what the syntax is to make that happen.

 

Any ideas?

 

Thanks!
