You can delete them by mtime or by ctime:

If by "message date" you mean the Date: header, then there's no easy way.

Yes Date header unfortunatly (seems i will have to write some kind of script for that)
Just to be sure just deleting mail files is safe? Or do i have to run some additional commands to recreate dovecots index files? I'm using Maildir.
Asking just to be sure that I will not screw up something.

Would something like the following work for the date header?
#!/bin/bash for msg in *; do if b4.py $msg 20080216; then rm $msg fi done
#!/usr/bin/python
datestring = get_dateline() ## FIND DATE HDR AND RETURN THE STRING yyyymmdd = format2yyyymmdd(datestring) ## CONVERT TO YYYYMMDD if yyyymmdd < sys.argv[1]: sys.exit(0) else: sys.exit(1)
In the preceding, would the deletions mess up maildir indices?
Thanks
