Nimbostratusrewrite email address
Anyone know if v9 irules can inspect an email header, and look for a specific invalid rcpt addr (e.g. someone@foo) which is not a fully qualified domain name, but rewrite it to someone@foo.com?
...
iRules certainly has this capability, though it would be a relatively complex rule to write.
You'd have to intercept the TCP data, and search through the contents to see if there were a misformed email address (probably with regular expressions) that needed to be transformed into a properly formed address.
You'd then, of course, have to know what to do to it to make it whole again. Assuming you only had the one instance where you needed to add ".com" to a domain, this wouldn't pose much of an issue. If you start having multiple conditions that need to be met, I.E. if x, add .com, if y, remove the last two characters and add oo.com, if z add .net, etc., etc., you can see how this would become complex very quickly.
If you're going to try this, I'd start by searching the forums, as well as taking a look at the stream profile information on your BIG-IP to see if they can lend some help.
