"Waiting to read mailbox while mail is being received: attempt #2" -- This is the message I get from ELM when I try to read my mail from ELM and Pine does not respond at all. A similar problem happened months ago and somebody told me that some kind of lock file is stored somewhere that prevent you from reading the mail. Where is that file? I can read/write on the file /var/mail/myusermailfile and the "from" command gives right output. What should I do?
