Hello folks,
One of our client was facing an issue while sending an emails from his VPS. He was receiving below error:
QuoteSMTP Error (-1): Connection to server failed
There are multiple possibilities for this error. To resolve this follow below instruction.
1. First check the exim status.
Quote# service exim status
exim dead but subsys locked
If you received this status then restart or start the exim service.
Quote#service exim start
2. If the above steps didn't work then try the following steps.
Sometimes this error may also cause due to a setting in the CSF firewall or another firewall. It might be caused by having the following set:
QuoteSMTP_BLOCK = 1
SMTP_ALLOWLOCAL = 0
You would need to change
SMTP_ALLOWLOCAL to 1 to enable Webmail to function.
That's all, enjoy !! :) ;)
