SMTP not sending emails on Appian 17.4

krishnak756 over 6 years ago

Implemented SMTP on 17.4 Appian server as per instructions on the link https://docs.appian.com/suite/help/17.4/Mail_Server_Setup.html but not receiving any emails.

Properties set are:

conf.mailhandler.mail.smtp.host=<our SMTP server>

conf.mailhandler.mail.smtp.auth=false

conf.mailhandler.mail.transport.protocol=smtp

The command line testing of SMTP on the same server works fine using our SMTP server. Any suggestions and/or logs in Appian that I can review to troubleshoot the issue?

Is the SMTP server you're using local to Appian? Or are you pointing to a mail server running somewhere else? I might check to make sure the name of the SMTP server in custom.properties resolves -- that is, if the server is local, I might make the entry "localhost" or 127.0.0.1. Depending on whether DNS is set up, pointing to a machine name might not be work and you'd likely need to specify an IP address of the SMTP server. You can test this by trying to ping whatever is specified as the SMTP server from a command line to see if you can see it.
