PROBLEM -: E-mail sending completely stops and fails with the following lines on debug.log :
[07-24 10:30:36] sche (INFO) Scheduler Sending Email[07-24 10:30:36] sche (ERROR) Scheduler Aborting email action 56620 because SMTP is not configured.
[07-24 10:30:36] sche (INFO) Scheduler Sending Email
[07-24 10:30:36] sche (ERROR) Scheduler Aborting email action 66955 because SMTP is not configured
As a wokaround to fix the issues you simply log into the server console , go into the section, and click save again to have emails start working again but after somedays the issue resurfaces
SOLUTION -:
1. Check the custom.ini file has the following parameter -:
SMTP_HOST=your-smtp-server-domain
Replace your-smtp-server-domain with the domain name/IP of your smtp server.
2. Add the following additional lines on custom.ini
SMTP_CONN_TIMEOUT=110000
SMTP_IO_TIMEOUT=110000
3. Restart the connect services to apply the changes
