It seems clear that the problem is around php openssl and imap but :

php7.0-imap is already the newest version (7.0.30-0+deb9u1).
openssl is already the newest version (1.1.0f-3+deb9u2).

GitMate.io thinks possibly related issues are #8050 (Quota issues ), #5233 (Share password by mail send on behalf issue), #2898 (Upgrade Issue), #1326 (Mail design), and #106 (Sharing broken when LDAP and Mail App is enabled).

[violoncelloCH]

this is probably an issue with the nextcloud rainloop app or the underlying rainloop software itself.
could you report this in the rainloop-app repository? (https://github.com/pierre-alain-b/rainloop-nextcloud/)

[tabp0le]

Do you have this unchecked? It can't be checked.

Also, the following is the required setup for Gmail. I can confirm it working.

[bibull]

Ok, i find the problem.

If i replace imap/smtp.gmail.com by the ip adress 108.177.119.108 it's work fine.

Is it normal ? it's a dns problem...

[violoncelloCH]

so this is a problem of your DNS resolver and not with nextcloud...
