Email not being - stuck in spool with waiting to deliver

Question asked by Frederic de Comarmond - 4/27/2017 at 8:47 AM

Unanswered

Hello,

I have recently migrated SM 14.x from one server to another.. While so doing I have installed SM 15.x

The migration went well, with all the domains and users loading on the interface.

I have also updated the MX record, and DNS has propagted well.

Emails started flowing, then 2 hours after now no users are able to send emails. Only incomings are flowing.

The spool is increasing and so is the waiting to delivery.

I went through the Knowledge Base and tried some solutions but none seem to help?

Woulld anyone have an idea please?

Thank you.

Hi Frederic. Right-click on one of the messages, go to View and then Recipients. What message do you see there? Does it say Pending or is it an error such as a 601 error? If it is a 601 error, you may want to check the DNS servers that you are using in SmarterMail and change them to Google's DNS servers (8.8.8.8 and 8.8.4.4). Once you do that, restart the SM service and then try forcing a send on one of the messages in the spool. If it leaves the spool for delivery, then you know it was a DNS issue.

Hi Linda.

Yes it say pending
No 601 error.
After several retries the email will eventually leave the spool.

Some pending have error messages like ' Too many spams from my IP'

I guess they are genuine reasons for staying in the spool.

Frederic, I sincerely apologize for the delay in my response. I wasn't emailed when you responded to this back on the 1st. I'm sure you have figured this out by now, but I wanted to follow up regardless. Please let me know if you are still seeing this issue and if you would like some help with it. Thanks!

I also face this kind of issues, once a while some of the emails are stuck in the pool though primary dns: 8.8.8.8. In a day 5 or 6 times i get this error... is there any IMAP/POP3 number of Connections has to be changed and i get the error message 421 - too many connections for some users and for some Internal Server error. any idea ? Thanks..
