A mail system consists of many parts. SquirrelMail does two things: allows you to read what's been delivered by other system parts to your mailbox, and allows you to instruct other system parts to send out mail that you have composed. VERP makes use of different sender addresses. To be able to collect mail from all of those and deliver them to your mailbox is out of the scope for SquirrelMail - check your SMTP server and local delivery solution. SquirrelMail can use variable sender addresses, but only if you manually configure them and choose one of them when sending mail. This isn't very suitable for VERP. If I were to tackle the problem I'd configure my SMTP server to use a catch-all address (that's the easy approach, although I generally don't like catch-all addresses) or define each and every VERP from address in the mail system (the harder but a bit better approach, which could be done with a script). In both cases I'd have them deliver to a special mail box. Then I'd write a script to mail out a test message to all recipients, but with different from addresses for each and every one for them (as described in VERP).
