I'm in a situation where I need to rewrite, sometimes, the recipients
of a message.
My basic problem is that I have two plugins:
1. recipient_foo
2. rcpt_ok (This is the vanilla version in qpsmtpd.)
In the first plugin I wish to make tests, and possibly rewrite the
recipient address. The intention is that rcpt_oks hook_rcpt function
will then test against the updated recipient - however that doesn't work.
(ie. If I try to modify $transaction->recipients() the current
recipient hasn't yet been added to it. Obvious since hook_rcpt
hasn't returned yet!)
The current qpsmtpd implementation pretty much does:
1. Reads : RCPT TO <[EMAIL PROTECTED]> from SMTP
2. For each rcpt_hook registered call them in turn until
we get OK/DENY/etc.
This means right now, without modifying rcpt_ok, I'm out of luck. I can
update recipient_foo to change the recipients only in a different stage
of the SMTP transaction.
(e.g. Like the "alias_rewrite" plugin[0] I can do the testing at
RCPT stage, and rewrite the transaction's recipients() list in
the DATA stage - but that doesn't allow me to work with a vanilla
rcpt_ok plugin.)
Ideally I'd like to be able to modify the recipient prior
to subsequent hook_rcpt calls - is that possible? I've looked around
over the source but I can't see a simple method of doing
so.
