I don't understand your question. The 'modify' operation applied on an
AT allows you to do whatever you want, assuming you give it the right
operation to apply. 'replace' will discard all the values and replace
them by the new values. Otherwise, 'delete' deletes some specific
values, and 'add' adds the ones you provide.
Isn't it enough ?
Aye, i understand it can be done through delete/add. My wondering was
about the possibility to perform the change using a single operation.

It does. What the ldif snippet you gave just do is to replace all
'mailAlternateAddress' values by the two values you provided. Isn't it
what you wanted to do ?
Otherwise, assuming you want to replace the oldmail@ value by the
newmail@ value, the correct ldif would be :
Yes, that's what was intended.
Check the LDIF RFC (http://www.ietf.org/rfc/rfc2849.txt
), you have
clear samples at the end.
Thanks for the pointer. I have visited the rfc before but didn't go
through the end of the document.
