Indeed, I don't see anything related to mails in the logs as well. Mails and invites got broken when upgrading from 2.5.0 to 2.5.2 for me, and it's hard finding out why because there is nothing in the logs at all. :see_no_evil:

[mserranom]

Hi @fnetX the only change in 2.5.2 is related to how the email address is stored in the tokens table (lowercase is now enforced): https://github.com/overleaf/overleaf/blob/master/hotfix/2.5.2/create-token-lowercase-email.patch

Do you have problems with any email address or only those with a lower/uppercase mix?

[fnetX]

Well, my issue is probably not exactly about mailing, sharing via email stopped working at all. I cannot share documents from [email protected] to [email protected], nor can [email protected] share docs to [email protected] - the invite doesn't even show up in the dashboard.

I can't find anything useful in the logs.

I now managed to get this from the logs via bin/logs -f web:

{"name":"web","hostname":"0b4b593a96b8","pid":157,"level":50,"err":{"message":"error sending message","name":"OError","stack":"OError: error sending message\n    at Object.sendEmail (/var/www/sharelatex/web/app/src/Features/Email/EmailSender.js:100:11)\n    at processTicksAndRejections (internal/process/task_queues.js:97:5)\ncaused by:\n    Error: 139984895788928:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:../deps/openssl/openssl/ssl/record/ssl3_record.c:332:\n    ","info":{}},"projectId":"6023e040b0d17200762abe3c","email":"[email protected]","msg":"error sending messages for invite","time":"2021-04-27T11:19:31.831Z","v":0}

How can I find out more? Probably related: #750

This fixed my setup, actually. I wonder why the behaviour changed, because it worked at the beginning. Never mind, now mail is working again. The explanation of these vars and troubleshooting is not very prominent tbh, but I can't care about that right now. Setting the SECURE var to false feels a bit off actually, and I wonder why this is necessary, since my server supports both STARTTLS and normal TLS :shrug:

[AugustoGarcia]

I was able to fix it using the following config, with a custom mail server with TLS enabled:

SHARELATEX_EMAIL_SMTP_IGNORE_TLS: "false" (mind the " " in all first three) SHARELATEX_EMAIL_SMTP_TLS_REJECT_UNAUTH: "false" SHARELATEX_EMAIL_SMTP_SECURE: "true" SHARELATEX_ADMIN_EMAIL: "[email protected]" SHARELATEX_EMAIL_SMTP_PASS: "yourpassword" SHARELATEX_EMAIL_SMTP_USER: "[email protected]" SHARELATEX_EMAIL_SMTP_PORT: "465" (587 does not work even if enabled) SHARELATEX_EMAIL_SMTP_HOST: "your.mailserver.address"

[mhsiggers]

It works for me as @fnetX suggests with:

SHARELATEX_EMAIL_SMTP_IGNORE_TLS: "false" SHARELATEX_EMAIL_SMTP_TLS_REJECT_UNAUTH: "false" SHARELATEX_EMAIL_SMTP_SECURE: "false" SHARELATEX_EMAIL_SMTP_PORT: "587"

I just add two points. I had to setup port 587, as I had 465 setup.

ports: - 587:587

The big issue for me is that I was using smtp.gmail.com as my host, but I have 2-factor authentication turned on on my gmail account. So for my password I have to use an app password as explained here.

I've uploaded a workaround in a gist: https://gist.github.com/scmanjarrez/8f8ded964e1aebd57721c2cd364bbab7
