    Hey guys, been a long time since I've logged on here (2 and a half years nearly) but I need a bit of help. We have a strange problem at work. Our email server, using a static IP, is not receiving mail properly - it recieves 80% of the mail it should but some clients cant send any in.
    Mail is being sent in by thee clients and they dont get any bounce back the mail just goes from their mail server and never hits ours which is quite strange. All our MX records are correct and pointing to our IP, reverse DNS is setup by our ISP so its mapped to our static IP as it should be and the ports are open for exchange/pop3/smtp on the firewall yet still people cant send in mail.
    However some people do get bounce backs - I got this from from a fellow tech who kindly emailed me the response he got when emailing me:


    Generating server: smoothwall.local

    tech@blahblahdomain.co.uk
    #< #4.0.0 X-Postfix; lost connection with mail.blahblahdomain.co.uk[**IP removed for secruity**] while receiving the initial SMTP greeting> #SMTP#

    Any ideas what could be causing this?
    Other bounce backs say nothing at all which is weird.

    Many thanks in advance - Andy

    Do you have access to maillog(or wherever postfix is logging)? I would expect more verbose output there than in the bounce message, plus any errors not directly related to that particular mail transaction.

    since it mentions smoothwall do you have the smoothwall add on smoothzap as we have had issues with this and smoothzap

    I would check if your smtp server requires a EHLO or HELO
