    I'm having email problems with webmail and IMAP. When I try to send email with Horde, I get this: There was an error sending your message: Failed to set sender: user@domain.net [SMTP: Failed to write to socket: not connected (code: -1, response: )]. I have read elsewhere that this is due to SMTP being blocked in csf, but I followed the instructions to set those to allow SMTP traffic:

    Code:
    SMTP_BLOCK = "0"
SMTP_ALLOWLOCAL = "1"
    There's also:

    Code:
    SMTP_PORTS = "25"
SMTP_ALLOWUSER = "cpanel"
SMTP_ALLOWGROUP = "mail,mailman"
    Anyway, stopping csf altogether doesn't fix the problem.

    When I try to send an email, I get this in /var/log/maillog:

    Code:
    Jul 18 19:30:54 hadrian imapd: LOGIN, user=user@hostname.domain.com, ip=[::ffff:127.0.0.1], port=[45588], protocol=IMAP
Jul 18 19:30:55 hadrian imapd: LOGOUT, user=user@hostname.domain.com, ip=[::ffff:127.0.0.1], headers=0, body=0, rcvd=38, sent=250, time=1
    I need to get email working. What else can I try?

    Sounds like you're logged into cPanel as the cPanel user and then went to Webmail as that user and tried to send an email. The cPanel user doesn't actually have an email account though. Create an email account properly and logout of cPanel.

    Log back into Webmail yourdomain.com/webmail using that new email account you just created. Your Webmail login would be the full email address for the username, and the password you set that new email account to have. Now try sending an email and see how it goes.

    No change. All of my clients are seeing this behavior, even without webmail altogether.

    From within your WHM, top right corner is a Support Menu. On that menu a link to Contact cPanel. Us that and put in a ticket so that cPanel Technical Support can come by for a closer look.

    Please do post back what you find out.

    Thanks!

    Was there a simple fix for this?

    I am seeing the same issue on one of our servers. I setup my own mailbox in a customer's account, and then (using a different browser), logged in via domain/webmail using the mailbox address/password. Upon trying to send a message to anyone (a domain on the same server, or somewhere else entirely) using Horde I see

    There was an error sending your message: Failed to set sender: xxx@xxx [SMTP: Failed to write to socket: not connected (code: -1, response: )]

    When you open webmail and go to send a new message, at top of that window does it show the Identity you'll be using to send that email?

    In the ticket mentioned above, EXIM was not running for some reason. Are you able to send email out from any other accounts on the same server or no?

    Also, if the issue is exim isn't running, check for that and restart it:

    Code:
    ps aux | grep exim
/etc/init.d/exim restart
    After it is running, tail /var/log/exim_mainlog to see if you show any errors occurring on startup:

    Code:
    tail -fn0 /var/log/exim_mainlog
    Thanks!
