Increasing check frequency wouldn't help with this. It could be some anti-spam measure (greylisting). Maybe your provider allows some mechanism to whitelist a domain and/or e-mail address, likely via the web interface (if there is one). > So in such instances, it would be nice to check for new mail once a > minute.

For an instant-like experience with e-mail you need push, not pull (e.g. like the IMAP IDLE extension). You would have to replace getmail with something like offlineimap or interimap (not familiar with either, so can't tell if they would actually work for that and/or fit your needs). If you want to explore this path I suggest you start a new thread and explain what such a system would need to achieve (e.g. full offline copy of all messages, sorting/filtering), *not how*, and if there are any objective or subjective constraints (e.g. e-mail provider that can't be changed, e-mail client you won't part with, etc.) Kind regards, Andrei -- http://wiki.debian.org/FAQsFromDebianUser
