domain alias: email answers issue

[Alessandro]

Hi all,
I have the "company.com" domain and the alias "company.it".

When "somebody@company.com" writes to "myself@company.it" the email arrives to my inbox. So simple.. but the destination appears as ".it", so if I try to answer the zimbra-webclient keeps "myself@company.it" in the "cc" fields.

It seems to me that the zimbra-webclient feels "myself@company.it" as a different address, not the mine.
To solve I created the single alias "myself@company.it" => "myself@company.com", and it works (yes, it is quite annoying: I already made the domain alias! but it works)


But I have the same problem with the other clients (thunderbird, smarthphone, etc.). I configure thunderbird for "myself@company.com", so it keeps "myself@company.it" in the "cc" field, and I can do nothing to solve the problem (in the client-side).


Nobody else had this problem?
I think the best solution is to rewrite the "To: xx" header in order to switch from ".it" to ".com" before the email arrives in the inbox, but I don't know how I can do.
Can the "Domain Masquerading" solve this problem? Or can I add an external header filter,made by myself? Or.. any other idea will be appreciated.

Thanks

Postfix "recipient_canonical_maps" resolves the problem:

content of /opt/zimbra/conf/recip
/^([^@]+)@company\.it$/ ${1}@company.com

postmap /opt/zimbra/conf/recip
postconf -e recipient_canonical_maps=regexp:/opt/zimbra/conf/recip
postfix reload

et voilà... The local destination address "@company.it" is rewritten in "@company.com" in all the emails.
And I don't need the single aliases for each account anymore.

I will have to pay attenction to the future zimbra updates, they should overwrite my trick.

No, it seems working only for clients in "$mynetwork" environment. For all other clients (all the world, as far the server will have the mx record referring to it) it doesnt' rewrite the adresses.

As far this is a postfix related question I will post it on the postfix mailing list.

Thanks

postconf -e remote_header_rewrite_domain=company.it

Finish (I hope..)
