    Hi,
    I am having problems with emails being sent from my server never arriving at their destination. I rent a VPS server, which is used for a number of FTP accounts, but emails for just one account, which is example.com

    At the moment if I go to MXTOOLBOX I get the following error:

    "SMTP Banner Check - Reverse DNS does not match SMTP Banner"

    So potentially this could be the problem. I then get this message from the helocheck@abuseat.org:

    "Reporting-MTA: dns; 329070.vps-10.com

    Action: failed
    Final-Recipient: rfc822;helocheck@abuseat.org
    Status: 5.0.0
    Remote-MTA: dns; mail.abuseat.org
    Diagnostic-Code: smtp; 550 *** The HELO for IP address 46.32.xxx.xxx was 'example.com' (valid syntax) ***"

    where blahblah.vps-10.com relates to the Server Name.

    I've set 'Send mail from account’s dedicated IP address' to OFF and the options for mailhelo and mailips to ON and also created these two entries for those files:

    mailips
    "example.com: 46.32.xxx.xxx
    mail.example.com: 46.32.xxx.xxx"

    mailhelo
    "*: example.com"

    Does anyone have any idea why my emails may be getting lost? And if so, what I can do to improve the situation? I'm presuming there must be some setting that I need to change and this will improve everything dramatically.

    Thanks in advance for your help!

    Cheers,
    Russ

    Well, I can't see anything. I've just had a good look through over the last few days, including for a few emails which were supposedly sent, but they are all showing as completed.

    There are some SMTP connections lost but they're all for IP addresses other than mine, so I'm guessing that's not the problem. I can't really find anything with any error message.

    However, I am new to EXIM and using a VPS. Is there something in particular I should be looking for?

    Best,
    Russ

    Here is a header from a recent email to one of my other email addresses. This one was received. However, does anything look strange here?

    Hello,

    I don't see anything out of the ordinary in that output. If Exim shows the message as "Completed" on the cPanel server, then it's likely filtered or marked as SPAM on the destination server before it reaches the user's inbox. Is the issue isolated to a specific destination such as Google, or multiple destinations?

    Thank you.
