Yes, it can, though it might be nicer to use the return path. This would
depend on you either submitting your email via SMTP (so that
your MUA sets the return path) or configuring Exim so that your username
is in the trusted_users list. If you really want to use the From: header
then the following will require some tricky fiddling.
What you can do is add a couple of routers at the start of the routers
section in the default configuration. The default dnslookup router will be
used if you aren't sending from your Yahoo! or Terra addresses.
from_yahoo:
driver = manualroute
domains = !+local_domains
senders = borrajax_listas@??? : borrajax@???
route_data = smtp.correo.yahoo.es
transport = remote_smtp
from_terra:
driver = manualroute
domains = !+local_domains
senders = hector@???
route_data = mailhost.terra.es
transport = remote_smtp
Then you need to set up authentication. In the main part of the
configuration file, set:
hosts_require_auth = smtp.correo.yahoo.es : mailhost.terra.es
Then you need to configure the authentication mechanism(s). This might
depend on what your ISPs support, but the following should be sufficient
if added to the authenticators section of the configuration file:
LOGIN:
driver = plaintext
client_send = ${if eq{$sender_address}{borrajax_listas@???} \
{: borrajax_listas : PASSWORD} \
{${if eq{$sender_address}{borrajax@???} \
{: borrajax : PASSWORD} \
{${if eq{$sender_address}{hector@???} \
{: hector : PASSWORD} \
fail }} }} }
