Regarding improvements to mail server capacity shortages

Recently, during our summer vacation, we experienced a surge in emails, causing our email server to run out of capacity.
We sincerely apologize to customers whose emails were returned to us without being delivered and for any inconvenience caused.
We have increased the capacity of our mail server, so we do not expect this type of thing to happen again in the future. Thank you for your understanding.
Thank you for your continued support.
