For an application like that (mail server), it might be beneficial to create the file system with bsize == fsize (e.g. both 8 kbyte), so you won't get any fragments at all. On a related note, many people seem to set minfree to 0%, in order to squeeze more space from the disk. That's almost always a mistake, because it increases fragmentation considerably, especially if the file system has many small write operations, and it reduces performance significantly.
