    Hi,

    We use email with an ISPConfig3 installation, up until now only on our local network and everything seems fine, but now we have clients who want to access their mail from outside our local network and they can send but not receive mail. These the postfix restrictions I have sent up in main.cf:

    ##Helo
    smtpd_helo_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_non_fqdn_hostname, reject_invalid_hostname, permit

    ##Sender
    smtpd_sender_restrictions = permit_sasl_authenticated, permit_mynetworks, check_sender_access mysql:/etc/postfix/mysql-virtual_sender.cf, reject_non_fqdn_sender, reject_unknown_sender_domain, permit

    ##Recipient
    smtpd_recipient_restrictions = reject_unauth_pipelining, reject_non_fqdn_recipient, reject_unknown_recipient_domain, permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, check_recipient_access mysql:/etc/postfix/mysql-virtual_recipient.cf, reject_rbl_client cbl.abuseat.org, reject_rbl_client sbl-xbl.spamhaus.org, permit

    ##Client
    smtpd_client_restrictions = permit_mynetworks, permit_sasl_authenticated, check_client_access mysql:/etc/postfix/mysql-virtual_client.cf

    Is the problem here or should I look elsewhere? I can see nothing that indicates a problem in the ISPConfig mail logs.

    Any help or advice is very welcome.

    Which exact messages appear in the mail log when you send a email to the account.

    Hi

    I just sent one of our remote clients ([email protected]) a mail. This is from the mail log:-

    Hi,

    I found some problems elsewhere and solved them. Now we have everything working, so the smptd restrictions seem to be good. Next step for us is to try to implement greylisting so any advice on that from anyone whose already done it with IPSConfig3 would be a great help.

    Thanks
    Brian
