It's perhaps not the most elegant solution but *touch wood* it hasn't caused me
any issues.

Unfortunately you have not provided enough information. At very least you

Is there a sensible way to configure postfix to allow these messages
with null sender addresses to be relayed without opening the smart
host up to exploitation?
Sending bounces is not exploitation, but the smart host (really
submission service) policy is up to the ISP. Ask them.

Not in this case, sending NDRs with a non-null envelope sender address is a
fundamental violation of the robustness requirements of SMTP. This goes

And then use postsuper -r ALL to requeue the messages.
The originals will get stuck again but the aliased addresses will be delivered
to your POP/IMAP/whatever server.

Unfortunately the damage is done. If your systems are secure then a few exposed

could try implementing amavis using the content_filter parameter (after
queue content filter). Instead of smtpd_proxy_filter (before queue content

First make sure that the domain you are sending to is set as a virtual mailbox
domain. It sounds like you've already set the virtual transport to dovecot
which is right. If you think mysql is the issue try making a virtual alias maps
hash file.

Also I can see that dovecot has also accepted the message so you must have
