Tárgy: Re: [exim] Saving Recipient Before Rewriting Recipient
Hello Paul,

everything stated below should be read as „should“, because I'm not very
sure about it. But probably it's some hint for further reading
(.spec.txt, section 31.2 for the 4.68 specs)

If you rewrite during SMTP time, your original recipient is „lost“.

„Normal“ rewriting occures as soon as all header lines are received, so
probably you could add some X-Original-Recipient header.

True. During transport it's to late to change the recipient (envelope).

You should not use SMTP rewriting (the „S“ flag forces rewriting at SMTP
time).
