  1. Hi, I have not still figure out why this issue happened. I had enabled logging for below classes in jasper log settings: org.springframework.mail.javamail DEBUG org.springframework.mail.javamail.JavaMailSenderImpl DEBUG Also added below logging in log4j2 properties file: logger.org_SpringFramework_Mail.name=org.springframework.mail logger.org_SpringFramework_Mail.level=DEBUG Still nothing related to emails are logged to log files. Finally I added <prop key="mail.debug">true</prop> to the applicationContext-report-scheduling.xml file. Thereafter, SMTP logs are coming to catalina.out file. I hope whenever this issue happens next, I can analyse the logs and sort out the issue.
  2. Hi, I am using Jasperreports CE 8.2.0. I have created around 750 schedules that will send reports to multiple customers on early morning hours, 3:00 AM - 5:00 AM. I am using Sendgrid as mail service. Everything was working fine till Monday, 03/07/2023. On Monday morning around 8:00 AM, I noticed that no emails were sent for that day. I switched my connection from Sendgrid to Mailgun and suddenly all the emails were send. To debug the issue, I contacted Sendgrid and they told me there were no SMTP connections from my end during that period. I also checked the jasperserver.log file and strangely, there were no logs during 3:00 AM - 5:00 AM. There were logs for the emails send using Mailgun though. Then I tried to send a mail with Sendgrid using telnet and it went successfully. Later I again switched from Mailgun to Sendgrid and tested sending emails, it was also working fine then. Below is my SMTP settings from js.quartz.properties report.scheduler.mail.sender.host=smtp.sendgrid.netreport.scheduler.mail.sender.username=***********report.scheduler.mail.sender.password=XXXXXXXXXXXXXXXXXXXXXXXXXXXreport.scheduler.mail.sender.from=abc@xyc.comreport.scheduler.mail.sender.protocol=smtpreport.scheduler.mail.sender.port=25report.scheduler.mail.smtp.starttls.enable=truereport.scheduler.mail.smtp.auth=true[/code]Please advice what could be the possible reasons for this issue?
