    Hi,

    I'm getting complaints that a customer cannot receive attachments from a certain domain. This is what they said when they try and send the email. This same domain receives attachments all day and only seems to be a problem when coming from these people.

    This box does have the ConfigServer mailscanner setup on it with CSF firewall. I have not had any issues until they complained about not receiving attachments from these people. This same domain has received over 600 emails today many with attachments, but this problem is persistant when attachments are coming from this one sender it seems.

    I tried searching the forum, but could not really find anything. The error looks obvious from what they sent, but I'm just not so sure that my Exim config is to blame.
    Anyone have any ideas?

    From the people trying to send attachment
    We connect to their mail gateway - ACCEPTED
    Told their gateway who we are - ACCEPTED
    Told their gateway who the mail was from - ACCEPTED
    Told their gateway who the mail is for - ACCEPTED
    Send the data - body and attachment(s) - TIMES OUT

    It appears that there might be a timeout issue involved in sending this file. Our
    suggestion is if they are running sendmail is to increase their data delivery
    timeout:
    O Timeout.datafinal=???? The AJC has it's timeout set to 30m. This is to allow
    sites with slow Internet connections time to send large files without timing out.

    Code:
    Connecting to   
    domain1.com. via esmtp...

    Still not luck finding anything about this. I'm assuming nobody has ever seen anything like this?

    Are the attachments compressed? (zip, rar) If not, try that.

    I'm being told it's a PDF. I'll see about compressing it.

    I appreciate your reply.
