    Hi,

    I tried to send bulk email to 30,000 of my subscribers but was met with some problems. I do not get such problem when using APF/BFD.

    I uses a software to send bulk emails through my cpanel server. I have created a user called newsletter@domain.com where my sending software will using this credential to send the emails. It does work for a while. After about over 600 emails, I will get error saying,

    Code:
    Using relay "domain.com"
    Trying SMTP host "domain.com"
    Opening Connection
    220-cpanel.domain.net ESMTP Exim 4.52 #1 Thu, 15 Feb 2007 04:42:43 +0800 
    220-We do not authorize the use of this system to transport unsolicited, 
    220 and/or bulk e-mail.
    HELO domain.com
    250 cpanel.domain.net Hello domain.com [203.121.47.217]
    MAIL FROM:<newsletter@domain.com>
    250 OK
    RCPT TO:<user111@yahoo.com>
    550-(domain.com) [111.111.111.111] is currently not permitted to relay through
    550-this server. Perhaps you have not logged into the pop/imap server in the
    550-last 30 minutes or do not have SMTP Authentication turned on in your email
    550 client.
    QUIT
    221 cpanel.domain.net closing connection
    

    I already added my IP address into CSF and LFD whitelist. I even tried turning off LFD but still happens. I leave it running overnight and when I come back the next morning, I get this error and the rest of the emails got rejected by my server for relay. Is that CSF related issue or exims?

    Hi abubin,

    The answer is here :
    This has nothing to do with CSF. You just need to connect to POP at least every 30 minutes for using SMTP.

    If you are using a program running from your own PC, a crude workaround would be to let your email client check your emails every 25 minutes, unless your program has some option for this.
    If you're using an online program running on your server, you could use the php function instead of the smtp one ?

    Good luck :)
