If it's caused by timeout, please try to increase time for below two Postfix parameters in main.cf:
smtp_data_done_timeout = # <- Default is 600s (600 seconds), increase to, for example, 1200s.
smtp_data_xfer_timeout = # <- Default is 180s, increase to, for example, 360s.
Restarting Postfix is recommended after changed its parameters.
I will certainly try that.
Thank you.
