user_1701 Is this for emails originating from the F5 or originating from some other device which has traffic traverse the F5 as its gateway to the internet?

Paulius - Its is orginating from some other device. F5 VIP is used for them to load balance the traffic between mail servers.

  This sounds like an issue that the F5 should not be used for... a) train users or fix client systems to use the correct email or b) put in rewrite login at email server you are load balancing to.

  user_1701 I am in agreenment with whisperer that the F5 should not be used for this purpose. This overcomplicates the configuration and when troubleshooting occurs in the future this will most likely be overlooked and cause even further delays when something needs to be fixed as soon as possible. Just because the F5 can do it doesn't mean it should do it. So the source device isn't something that you control or that it is even a mail server? You really need to speak with the end user that wants this adjustment and have them explain why the source device cannot be corrected to show the correct souce email.

    whisperer Paulius - Yes. Thats right. Currently thers is an ongoing migration for changing it permanently on the mail server. Until it's completed we need interim solution in F5 to get the domain changed.
