I'm looking at how to warn users of an old format of email address. We used to be in sub-domains, [email protected] and now we use Google Apps for Education on one domain of [email protected].
We have exim forwarding email from [email protected] to [email protected] and what I'd like to do now is to flag all those messages so that users can find all the messages that are still using the old form of address. The best plan to date is to alter the subject line so instead of Subject: test message the user will get Subject: [Obsolete address [email protected] used] test message There are drawbacks to that plan, especially with anything that does any kind of digital signature based on the contents of the subject line, however the users have had 18 months to convert anything to the new address so hopefully we're only picking up a tiny amount of mail (and a whole lot of spam) I was looking at "headers_rewrite" but that seems to be restricted to addresses, so sysfilter looked like a good option or filtering a transport through a script to make the change. I wondered if anyone had done something similar and if so, what did you use? -- Jonathan Knight IT Services Keele University -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
