**Your software**  
My Mautic version is: 2.82  
My PHP version is: 5.6.37  
My Database type and version is:

**Your problem**  
My problem is: Have email config set to send “immediately”. If i send more than around 1100-1200 (not sure when it quits exactly) out of 2000 emails, the status bar which usually take a while to update after every 100 emails sent, goes quickly to 1300,1400,1500… 2000 and I know it is not sending emails anymore. I’m on my own VPS and have not put any restrictions on emails sent. Ideas? Alternately, when I send a segment email and I knew that the queue with the correct cron job would work, I could switch to this for these email jobs. It really bugs me cuz now I have no idea who didn’t get the email.

These errors are showing in the log:  
[2022-03-18 16:13:41] mautic.ERROR: [MAIL ERROR] Expected response code 250 but got code “”, with message “” Log data: \>\> MAIL FROM: \<\< !! Expected response code 250 but got code “”, with message “” (code: 0) (send)    
\*\*\*\*could still be trying to send some mails that weren’t deliverable yesterday?

Steps I have tried to fix the problem: not sure what to do here…
