Subscribing by email

Typically we manage our mail lists by direct editing. A typcial 
record in a file looks like:
<[email protected]>^tfirst_name last_name (^t is a tab which I 
represent here since you can't see a tab.)

We do this because some people don't use easily recognizable names 
for their email address. It is rare, but some look like 
[email protected]. Should I need to do something for Bill Smith, 
I may not recognize bill3425 as his email address. But, I can search 
for Bill and find his record if I have his full name in the record. 
And, majordomo uses this just fine.

Now I have a need for another individual to maintain a few of the 
lists, and the easiest way for him to do this is be email. Email 
message to [email protected], contents of
approve password zubscribe test <[email protected]>^tBill Guion. The 
zubscribe works just fine, but only the email address 
([email protected], no <>'s) gets appended to the file.

Is there a way to subscribe by email and get the format I want in the file?
