sitesme Posted October 23, 2019 Share Posted October 23, 2019 Not sure if this helps you but I have “fixed” the annoying messages by creating an email filter under our WHMCS cPanel domain. Just create the email filter, copy/paste the exact subject on the emails that you want to block and choose “send to another folder” (trash for example) or simply choose “discard all messages”. This is woking fine for me. Never got any of those notifications. I was getting about 15-30 per day. 0 Quote Link to comment Share on other sites More sharing options...
Mark Coates Posted November 7, 2019 Share Posted November 7, 2019 hi all i believe i have found the issue to this. since my last posting i have not had any of these until 2 days ago when i did a migration for a new client of 9 sites to my vps. since the upload and the sites was being used the errors started again. this cause was the memory on the actual vps so i have increased this again and now the issue has now stopped. hopefully this issue could help out some of you guys and as for this only happening with a certain update of WHMCS im wondering if this is because the updated version requires a little more memory to process the email/ticket feature. 0 Quote Link to comment Share on other sites More sharing options...

CCSupport Posted September 26, 2022 Share Posted September 26, 2022 Upgraded from WHMCS v7.10.3 to v8.5.1 including upgrading from php 5.6 to 7.2...and surprise surprise we are also having the same issue as mentioned by many.One or more POP3 connections failed:-----General Enquiries <our_email_address>Error: read failed - connection closed?----- I have checked all ticket systems and they work fine. However, erratically receiving the error email. Tried changing mailbox passwords, ports, checked memory usage, checked WHMCS/CRON PHP versions. I am going to try the temp fix of copying the bootstrap file to WHMCS root...but this partly goes against the reasoning of moving the CRON folder in the first place. I really do hope this bug/issue is fixed...because from a security perspective it's not good for us. 0 Quote Link to comment Share on other sites More sharing options...
Dzineer Posted May 19, 2023 Share Posted May 19, 2023 On 11/26/2018 at 12:29 AM, mustardman said: Perhaps you didn't null the output? php -q /home/mysite/whmcs_crons/pop.php >/dev/null 2>&1 With the ">/dev/null 2>&1" added you will not get the "Mailbox is empty" messages every 5 minutes. You will still get errors like the POP3 connection error. I am here because we also started getting the POP3 connection error messages after we upgraded to 7.6. We use gmail and it's not like we can do anything about it on that end. I sure hope someone finds a solution because these messages are going to be annoying. *** THIS IS THE CORRECT ANSWER. So do I fix this? 1. You must login to your root of your server or have access to the cron service inside your linux box. 2. crontab -e (this will open up the crontab in editor mode) Look at your cron tab it probably looks something like above Here is what mine used to look like: */5 * * * * /usr/bin/php -q /var/www/html/crons/pop.php change it to something like this: */5 * * * * /usr/bin/php -q /var/www/html/crons/pop.php >/dev/null 2>&1 Then save it. Note: that the path /var/www/html/ is where your WHMCS installation is located. So, if your location is somewhere else, be sure to find that first. 0 Quote Link to comment Share on other sites More sharing options...
primitiveshaun Posted December 3 Share Posted December 3 Was a route cause ever found for this POP3 Error emails? I've had a support ticket open but just seem to get quick-fire responses. It seems to haver happened non-stop for about 3 months every year since moving to WHMCS, then on sporadic other occasions. So far I've been told it resource issues - confirmed this is not a problem. I've then been told to decrease the POP import cron frequency. I replied to say it's currently set to run hourly, support then advised to increase the cron frequency. I'd already spoke with my hosting provider, they have had the issue reported in the past and says it looks like the code isn't handling opening new/refreshing POP3 connections correctly. WHMCS support don't seem interested in investigating or fixing - current resolution offered is ignore the error emails! We've hit a few other bugs in the core code already and I'm considering if it's worth the effort keeping WHMCS or not... 0 Quote Link to comment Share on other sites More sharing options...
