Server retries to send mails way more often than 30 minutes


#1

sending mail fails, it says retrying in 30min , but it did retry 2000 times in 1 hour
This did happen before the out of disk space segfault

Sample line of the log (they are all the same) :
2018-01-26 13:54:04: WARNING: Error sending mail to "paaa@aaa.net". FTP: weird server reply(ec=8), Got unexpected smtp-server response: 554. Retrying in 30m

tail -n 10000 /var/log/urbackup.log| grep ‘2018-01-26 13’ | grep ’ WARNING: Error sending mail’ |wc -l
1953

Apparently it tries in batch (a count in each line for each minutes in the last 3 hours before the crash)

for NUM in {1…60} ; do tail -n 100000 /var/log/urbackup.log| grep “2018-01-26 11:$NUM” | grep ’ WARNING: Error sending mail’ |wc -l ; done
