dynamically change sender address on external mails 1

[simonjcook]

Does anyone know whether it is possible to dynamically change the from address on an email as it leaves the exchange environment?

ie. sender@abc.com sends message to the internet and the from address is dynamically changed to sender@def.com

Any help in this area gladly received.

Thanks for the feedback,

I did search prior to posting.
I did feel this question must have been asked previously but my searches did not return anything relevent.
If you know the URL of a relevent post that would be useful.

Set sender@def as the primary in ADUC?

Thank you for the the link Pat, much appreciated.

It looks like there is no elegant solution to this.

The users in domain abc.com are transferring to def.com.
def.com and associated mailboxes are hosted by a seperate company.
The users are sending from the existing abc.com infrastructure and all replies should be routed into the new def.com infrastructure.
The replies are subsequently routed back to abc.com via the targetaddress AD property / alternate recipient.

There is no requirement to be selective for the senders address.

When the users physically transfer to def.com the targetaddress / alternate recipient will be removed from the def.com mailbox, mail will be delivered locally and they can continue to work as normal.

The best solution in the linked post might well be using a pop3 client where the reply address is usually a free text field.

One idea I've just had;
Use recipient policy to set a new primary smtp address of def.com for each user in the abc.com environment.
When they send externally, the reply address will be def.com.
They will still be able to receive mail on their abc.com address as it would now be a secondary smtp address and the environment is configured to route mail inbound for that domain.
Possible downside - if anyone sends internally to a def.com address it will resolve to an internal recipient and not be sent outbound...
Although that shouldn't be a problem we are currently diverting mail back to that environment anyway - so the outcome is the same...
(might be missing some finer points here).

noveyron is on the same wave-length...

Is the solution valid?

My interpretation of your question:

ABC is hosted on internal server A, DEF is hosted on external server B, and you want to find a solution that will allow users on internal domain ABC to send as external domain DEF?

I'm not sure the above solution would work effectively, there would be numerous issues with it.

Do you have RPC over https access to the DEF server? (I may be thinking a complete load of rubbish here )

Sounds like you need to change the masquerade domain in the SMTP connector. That isn't dynamic but it does change the SMTP address as you requested.

 

[simonjcook]

Another interesting solution, thank you.
The only issue I see with the masquerade domain is that not all users are transferring from abc.com to def.com at the same time.
Also, users have elected to change their name component of their email address at def com (usually to shorten it).

Therefore masquerading the domain is not a viable solution.

Thanks to everyone for responding to this post.
I think Noveyron gets the star and who beat me by 15mins... (I was still typing)...
