with my old smtp settings it works fine. just when i switch it... where should i check ?? i dont have a plan anymore

if you need any more infos pls just ask.


this is obviously an issue on the smtp server configuration.

Please throw this "relay access denied" message into your favorite search engine to get the first basic info about this message and the reasons why this appear.

If the old settings work, i'd recommend you stay with the old settings.

FYI relay access denied means exactly that - your SMTP server is not allowing your host to relay mail through it. Add the sending host to the /etc/mail/relay-domains file if you're using sendmail. If you're using Postfix, or some other MTA, then RTFM to see where you have to make the change.

got it fixed. it was a problem with the sophos i think..

but now i dont get any email notifications. the cron jobs are running with ajax (didnt work yesterday the whole day.) The cronjob is running perfectly but it just doesnt send any mails.
and now i tried to switch it to cron. maybe that will help but i dont know.

a local cronjob did solve the problem. i have no clue why ajax didnt work.

Could be a mail server issue as well. Check the logfiles of owncloud and your mailserver.
