    just contact the database where your ip get blacklisted ask them to remove it

    If it is a cpanel server you can enable extended login so that you can track down all details if you are suspecting a spammer.

    you can edit exim.conf file and use
    log_selector = +address_rewrite +all_parents +arguments +connection_reject +delay_delivery +delivery_size +dnslist_defer +incoming_interface +incoming_port +lost_incoming_connection +queue_run +received_sender +received_recipients +retry_defer +sender_on_delivery +size_reject +skip_delivery +smtp_confirmation +smtp_connection +smtp_protocol_error +smtp_syntax_error +subject +tls_cipher +tls_peer

    Use this to find out everywhere it's blacklisted and get started with delisting.

    How did you come to know the IP has been blicked listed? If your IP is blacklisted, you should have received the bounced back emails if the destination server rejects your email. Your script should be able to send emails but must be bounced back with the reason of "unable to deliver"

    Hello,

    On a side note, if your server uses Exim, it can be set to send and process mail from a different, clean IP, temporarily until the current sending IP is deemed clean. Your host should be able to help you with this.

    You must first secure your box. Ask your provider, they can give you a hand.
    I have a tool to check the reliability of any SMTP server; check my sig for further details. Once you have secured it, ask for removal.

    If your ip is blacklisted you can still send email to mail servers that do not use blacklist checks. There are lot of this servers.
    One of my mail servers was blacklisted because of no existing PTR record. Im have changed IP address and asked my ISP to make an PTR record.
    I am also have an web tool to check if ptr exists/blacklisted. Try link to my website is in my profile.

    It may sounds odd, but you also have to check if it is only you, who use this IP.

    hi...

    First of all check your mail headers before sending email through php. Is your server's ip address has Reverse DNS lookup entry?.

    Try to read about (sender id). You have to SPF record against your IP address in the DNS server. Domainkeys is also very helpful.

    If you follow all above options then ask to database where you ip is blacklisted otherwise It'll be again happen.

    Regards
