Hi!
In this context of a DUL configuration of Exim, I want to ask for help
or a suggestion in the handling of restricted smarthost found at many
freemail services. In my case the freemail provider is GMX.
If I want to use GMX's SMTP server as smarthost, I first do POP3 for
every GMX sender on my host. After that the SMTP after POP3 condition is
fulfilled.
I then do address rewriting for envelope and header addresses by
translating local users with a fantasy domain to valid GMX mail
adresses. For non-system mails this also sets the MAIL-FROM address
according to the envelope. This does the job for "normal" users' mails.
But I still have a problem with Exim's error messages, which should be
delivered locally in my understanding. But they are sent back to the
rewritten GMX addresses, so Exim uses the smarthost with an unspecified
MAIL-FROM and fails.
Now, I am stuck with this last problem of undeliverable error mails,
still I am quite happy with the address rewriting stuff.
I would be even more satisfied, if anyone on this list has an answer for
these system mails which tend to answer an empty MAIL-FROM during the
smarthost communication.
Bye
Holger
