Gmail not sending emails

[pgamaster]

When I try to test sending from Gmail - nothing happens, it just hangs.... waiting for localhost....
Did you test it on your end?

I am testing your package to replace a monitoring package that does not support https websites. I like the response time graphs - they should help me tune timeouts so that I detect slow website performance as well as website outages.

I am having problems configuring both a custom mail server (provided by pair.com) and Gmail. If I specify port 465, the Test button hangs on both mail gateways, the same as pgamaster describes.

Using port 587 on pair.com results in "org.springframework.mail.MailSendException: Failed messages: javax.mail.SendFailedException: Invalid Addresses; nested exception is: com.sun.mail.smtp.SMTPAddressFailedException: 554 5.7.1 : Client host rejected: Access denied".

Using port 587 on Gmail results in "org.springframework.mail.MailSendException: Failed messages: com.sun.mail.smtp.SMTPSendFailedException: 530 5.7.0 Must issue a STARTTLS command first. "

Thanks, Norbert
