I'm not entirely sure, but it looks like nnimap has its own server
variable governing expiration/expunging: ‘nnimap-expunge’

>From the manual:

     When to expunge deleted messages.  If ‘never’, deleted articles are
     marked with the IMAP ‘\\Delete’ flag but not automatically
     expunged.  If ‘immediately’, deleted articles are immediately
     expunged (this requires the server to support the UID EXPUNGE
     command).  If ‘on-exit’, deleted articles are flagged, and all
     flagged articles are expunged when the group is closed.

     For backwards compatibility, this variable may also be set to t or
     nil.  If the server supports UID EXPUNGE, both t and nil are
     equivalent to ‘immediately’.  If the server does not support UID
     EXPUNGE nil is equivalent to ‘never’, while t will immediately
     expunge ALL articles that are currently flagged as deleted (i.e.,
     potentially not only the article that was just deleted).

Does that help?
