I am refering to this topic in the old forum: https://forum.owncloud.org/viewtopic.php?p=120301
As a recap of what has been done and said:
Steps to reproduce
1. Personal settings -> Activity: Tick every Mail-Notification-Checkbox
2. Create/Delete/Change files and foldersExpected behaviour
Receiving an email with changes done to the files and foldersActual behaviour
Receiving no emailServer configuration
Operating system: Ubuntu 16.04 LTS (GNU/Linux 4.4.0-22-generic x86_64)
Web server: Apache/2.4.18 (Ubuntu) - 2.4.18-2ubuntu3.1
Database: MariaDB 10.0.25-0ubuntu0.16.04.1
PHP version: PHP 7.0.4-7ubuntu2.1
ownCloud version (see ownCloud admin page): ownCloud 9.0.3 (stable)
Updated from an older ownCloud or fresh install: 9.0 fresh install, 9.0.1 and 9.0.3 updated
ownCloud log (data/owncloud.log): pastebin.com/raw/BNhuu5EmSpecial configuration (external storage, external authentication, reverse proxy, server-side-encryption):
Separate hard drive mounted in /.../data, ownCloud Test email workingPossible cause:
{"reqId":"w7iRpVG1Y6XyQYs6rogn","remoteAddr":"1.2.3.1","app":"sharing","message":"Can't send mail to inform the user about an internal share: Address in mailbox given [@] does not comply with RFC 2822, 3.6.2.","level":3,"time":"2016-06-07T18:31:48+02:00","method":"POST","url":"\/core\/ajax\/share.php","user":"comp"}
We did set a valid (and existing) address in the form of a.user@domain.com for the user and did verify the mail settings by sending a test mail which we received within seconds.
Perhaps the log excerpt with the error message I posted is unrelated after all. We updated to 9.0.3 a couple of days ago, tested it, haven't received a notification email and nothing shows up in the logs.
After setting the logging level to debug and testing it again, the log doesn't look like it's sending any email at all: http://pastebin.com/raw/8JgVGbPX
The mail server log shows the test mail we sent but nothing more. No mails were blocked.
We appreciate any help or ideas to solve the problem. Thanks in advance!
