Hello Maxim: I followed what you suggested the last time I asked about this (13th july) but for some reason I can’t get it to work. Considering my procedures and the Error I get what can I be doing wrong? - Is there another way to send the link to my attendees without using the email feature? (i.e. create an invitation email with a password, create the link, and copy these into an ordinary email). - I tried to do this pasting the link into the browser of my laptop but it does not open the access to OM (example link created: http://localhost:5080/openmeetings/hash?invitation=6c608020-c92d-42bc-98d9-763cfb0a1bb3&language=1). My laptop runs on Windows XP and no one is supporting XP anymore. Could this be the cause or am I doing this wrong?
set up gmail smtp https://support.google.com/a/answer/176600?hl=en I chose: Gmail SMTP server >From here I went to: https://support.google.com/a/answer/6260879?hl=en because I had to make sure I was enabling “Less secure apps” correctly According to this page, to be able to enable “Less secure apps” I had to access Google Admin Console, to be able to do this I had to create a GSuite account with a non-gmail email from my website, verify my domain as usual, and apparently I’m going to be invoiced if I want to keep on using this. After going through this adventure crossing rivers, through swamps, under and over the ocean, I finally installed OM with the following data: smtp_server: smtp.gmail.com smtp_port: 465 mail.smtp.starttls.enable: 1 I have tried to get emails sent from the room (Public Video And Whiteboard Room) using the following email information: system_email_addr 1) the email registered as the user email when installing OM (my website email), It is the same email used as Admin of Gsuite; 2) another gmail: myem...@gmail.com email_username myemail@gmail or mygsuiteem...@mywebsite.com or my OM username (not an email) email_userpass password used to enter myem...@gmail.com or my password used to enter mygsuiteem...@mywebsite.com or my OM password, respectively Each time I changed the configuration in the frontend I logged out and restarted Red5 to make sure changes were effective, then went into the room and sent an email invitation (with password activated and having created the hash link) myGSuiteemail: if I had an email called john...@mywebsite.com managed through my website, now I have an email with that same name managed through Google’s Gsuite but although it looks like gmail.com it sends emails as if it were john123 from my website. What I have found in my OM log is the following (the same in all cases): EBUG 07-30 20:11:03.061 o.a.o.c.m.MailHandler:236 [taskExecutor-1] - Message sending in progress DEBUG 07-30 20:11:03.062 o.a.o.c.m.MailHandler:237 [taskExecutor-1] - To: "email of person I am inviting" DEBUG 07-30 20:11:03.062 o.a.o.c.m.MailHandler:238 [taskExecutor-1] - Subject: "invitation sent" DEBUG 07-30 20:11:03.062 o.a.o.c.m.MailHandler:199 [taskExecutor-1] - getMimeMessage DEBUG 07-30 20:11:03.062 o.a.o.c.m.MailHandler:162 [taskExecutor-1] - getBasicMimeMessage DEBUG 07-30 20:11:03.136 o.a.o.c.m.MailHandler:205 [taskExecutor-1] - setReplyTo "Email registered for “user” when I installed OM" (It doesn’t change when I change emails in the frontend Configuration) DEBUG 07-30 20:11:10.139 o.a.o.c.m.MailHandler:277 [org.springframework.scheduling.quartz.SchedulerFactoryBean#0_Worker-3] - sendMails enter ...
