Email ServiceProblems logging in to email via webmail due to overload
Due to update which overwritten some cusotm values in startup script, our system was not allowing new connections to the server over the default limit. This caused logging in to webmail hard as your request had to wait for free connection.
Thanks to user reports, the issue was spotted and fixed. The fix was added to out automation templates (increased ulimit and setup systemd template including custom value) so we should not run into this issue in the future.
