There's a ringing endorsement of Verio. They told me that the server had a"group mail file" and all the users had their mail stored together. If I installed Dovecot, they said it would split the mailboxes up into individual files, and reduce the load on teh server, thus allowing it to better handle large mailboxes. I guess they are just making it up as they go along... thanks for the info though. I suppose I will seek an independent email host somewhere and have their mail forwarded, or upgrade my server on verio.
That sounds like you're using UW-IMAP with mbox files currently, which gets slow with large mailboxes. For that Dovecot would help, probably even by staying with mbox file format, but even better if you switch to maildir format.
