    Hi!, I've been looking for this trouble in the forum but I did'nt found an answer to help me, and I need this to make it works.

    Here is the thing, I've installed Postfix with courier and mysql.
    I can create accounts and access through squirrelmail, I can send and receive mail from my own domain, I can also send mail to external server (like gmail, hotmail, outlook, etc... ) but when I receive an email from one of this accounts (ex: gmail) is reject.

    I've already check mail.log and it doesn't show anything, there is no change in it. I also make a test with an online smtp test. And it shows:

    SMTP Reverse Banner Check OK - xxx.xxx.xx.xxx resolves to xxx.xxx.xx.xxx
    SMTP Reverse DNS Mismatch Warning - Reverse DNS does not match SMTP Banner Ignore
    SMTP TLS OK - Supports TLS.
    SMTP Connection Time 0 seconds - Good on Connection time
    SMTP Open Relay OK - Not an open relay.
    SMTP Transaction Time 0.983 seconds - Good on Transaction Time

    MAIL FROM: <[email protected]>
    250 2.1.0 Ok [172 ms]
    RCPT TO: <[email protected]>
    554 5.7.1 <[email protected]>: Relay access denied [140 ms]

    So, I don't know what to do, I've tried everything

    Seems to be SMTP Reverse DNS Mismatch Warning - Reverse DNS does not match SMTP Banner the error, or perhaps not. Can anybody sugges anyting please?

    Thanks in advance!

    Sorry for my english

    for the record

    when I use telnet localhost 25 it works fine
    but when I do it from external it doesn't connect, then I open it through 587. Does it need to be on port 25? I've tried to open it, but I couldn't

    Please make sure no firewall is blocking port 25. also make sure your ISP doesn't block port 25.
