Hi, Is it possible allow the use of special characters safely in the local part of a email address. We have a need to be able to accept emails that include special characters like ! e.g. joe!b...@example.com
When trying to send a test mail on a test server I get 'Relay Access denied' ``` postfix/smtpd[83186]: NOQUEUE: reject: RCPT from unknown[192.168.0.62]: 554 5.7.1 <joe!b...@example.com>: Relay access denied; from=<u...@test.com> to=<joe!b...@example.com> proto=ESMTP helo=<example.com> ``` I found a old post from 2012 where some parameters were recommended but with great risk. Even with these settings I could not get it to work and I haven't found anything else as of yet. http://postfix.1071664.n5.nabble.com/special-characters-in-mail-address-td47792.html So far I have tried a couple of different configurations parameters but nothing has worked. I have been reviewing parameters smtpd_relay_restrictions and smtpd_recipient_restrictions as these seem to be where it is getting blocked using the option reject_unauth_destination. main.cf ``` smtpd_relay_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, check_recipient_access proxy:pgsql:/usr/local/etc/postfix/vrfy.cf, check_client_access proxy:pgsql:/usr/local/etc/postfix/client_access_topten.cf, check_recipient_access proxy:pgsql:/usr/local/etc/postfix/rbl_policy.cf ``` Does anyone have a tips or pointers on what I could do here. postfix stable 3.5.9.
