The last access time is generally not needed, especially for Maildirs. 
On our setup, Postfix and Dovecot don't care.  I always mount as many 
file systems as possible with 'noatime'.

(Our IMAP Maildir storage is a 4-disk RAID 1+0 array with a few million 
individual messages across a lot of accounts.)
