Problem with mailalternateaddress field

[Rafael Angarita]

    Hi,

    I'm having some problems with the mailalternataddress field when I try to send a message using it instead the real mail address in my qmail-ldap cluster:

    - If  I telnet  port 25 of the mailhost with the mailbox the delivery is succesfull.
    - If I telnet port 25 of  another mailhost  in the cluster the mail is returned with the message:

Hi. This is the qmail-send program at ms03.mydomain
I'm afraid I wasn't able to deliver your message to the
following addresses.
This is a permanent error; I've given up. Sorry it didn't
work out.

<myaddress@domainwithmorethan30chars>:
ldap_lookup: init successful, bind successful
ldap_lookup: search for
(|(mail=myaddress@domainwithmorethan30chars)(mailAlternateAddress=myaddress@domainwithmorethan30chars))
succeeded
Sorry, no mailbox here by that name. (#5.1.1)

    The error only occurs when the mailalternateaddress is larger than 30 chars if it is not, the message arrives with no problem

    How can I fix this? is there any patch to solve this?

    Thanks for your help,
