Email whitelisting expression

Question

Hi, 
 
 I need to whitelist an email id ( envelope-from ) which is something like btv1==330be1b068d==username@website.com . Each time, the random id in the envelope from changes ( for ex: btv1==110be1b068d==username@website.com ). So how to whiitelist these kind of email ids? What kind of expressions should I use? 
 
 Thank you.

Hi, 
 a little late but since it's unanswered ... 
 Assuming you are on Puremessage f. Unix, you are probably looking at 'whitelisted-senders' which in turn has a match type 'email (see etc/lists.conf). 
 man PureMessage::List should give some guidance to allowed wildcards and type dependent match exceptions. A first starter (just made up, please check for alternate facts and mileage thoroughly) might look like: 
 pmx-list add whitelisted-senders 'btvl==*==username@example.com' 1 row affected 
 pmx-list test whitelisted-senders 'tvl==123123123d==username@example.com' tvl==123123123d==username@example.com did not match (since initial 'b' is missing) 
 pmx-list test whitelisted-senders 'btvl==123123123d==username@example.com' btvl==123123123d==username@example.com matched 
 pmx-list test whitelisted-senders 'btvl==123123123d==username@example.com==username@example.com' btvl==123123123d==username@example.com==username@example.com did not match 
 '*' wont match on '@' or '.' and thus wont 'consume' '123123123d==username@example.com' 
 Hope, this provides a starting point.
