Ho realizzato un server mail postfix che si appoggia ad un relay esterno. Le mail vengono spedite correttamente.
Non riesco a capire perchè le mail mi arrivano con un mittente nella forma:

utente§domionio.it

L'invio sui log appare giusto:

Quote:

6AF84788058: from=<utente@dominio.it>, size=706, nrcpt=1 (queue active)...
Jun 6 16:13:57 WebServer postfix/smtp[3836]: 6AF84788058: to=<xxx@gmail.com>, relay=miail.esterno.it[]:25, delay=1, delays=0.06/0.01/0.49/0.47, dsn=2.6.0, status=sent (250 2.6.0 704 bytes received in 00:00:00; Message id NUV62504 accepted for delivery)
Jun 6 16:13:57 WebServer postfix/qmgr[3827]: 6AF84788058: removed

ho creato anche il file sender_canonical in modo che associasse:

utente§dominio.it utente@dominio.it

Ma non pare che la cosa funzioni.

Dove posso sbagliare???

Il mio file di configurazione è:
