[dev] IMP: trigger getmail upon "refresh" button press

[Michael J Rubinsky]

Quoting Sebastian Birnbach <birnbacs at gmail.com>:

> A local IMAP server keeps my users' mails, and IMP is used as frontend. The

Nothing out of the box, no. This really sounds like a job for the IMAP  
server/mail infrastructure.  If you really wanted to, you maybe able  
to do something like touch/create a file when the user's session  
starts (using any of the IMP hooks that are fired once per session)  
and unlink the file when the session ends (via  
register_shutdown_function in that same hook), then check the state of  
that file from some cronjob?
