Dropped Server Connection

  • We have about 700 users. Sending to all the users, i get a server dropped connection error a couple minutes into the process. As an administrator, I get the email, but I’m afraid some of the users are not getting the email and maybe I’m getting it since Administrator starts with A ?? We’re using an SMTP Mailer (the one by wpecommerce) to send mail from the site. I’m not sure if it’s a host setting for timeout or something in the plugin or wordpress to adjust but any ideas would be appreciated.

    Thanks!

    A simple test would be to create another user who begins with “ZZZ” or something like that which will ensure they are at the end of the alphabet.

    Where do you see the Server Dropped Connection message? Is it in a log file or displayed on the browser?

    There are all sorts of things which could affect this. On the Email Users side, about the only one which would make a difference is the BCC limit setting as it dictates how many calls to wp_mail() are actually made.

    On your hosting side, there are all sorts of limits that I’ve heard about, the most common being no more than X emails can be sent per hour and/or no more than X recipients for any one email. I’ve seen others (like no BCC recipients) but these tend to be much less common.

    I am not familiar with the SMTP mailer you’re using, I’ve only used WP-Mail-SMTP myself. Compared to some other users I’ve helped, 700 users isn’t a large number so it shouldn’t be a problem unless your host enforces some limits.

    Thanks for the fast response Mike. The server dropped is displayed in my browser. I’ve just bumped up the timeouts with the .user.ini file to include
    memory_limit 256M
    max_execution_time 120
    max_input_time 120
    So perhaps that will help. I’m using Godaddy and their relay-hosting server which allows for 1000 relays per day which they say is the only limit on that for SMTP. Hopefully that will all help. I’m also going to try the Postman SMTP because it includes a log file which my current smtp mailer doesn’t so I can see without doing too many experiments on our user base ??
    Thanks for your help!

    Postman has a TCP Read Timeout setting that you can modify if the connection to GoDaddy drops too soon. And a Log and Dump mode so that you can experiment without annoying your user base ??

    Wow very cool. Looks like your plugin will help me a lot. Cool that you saw my post over here, thanks for responding! I’ve used a variety of the different SMTP mailers but yours looks like a lot of improvements.
