Reply To: Attachment Link in Mails are broken

Hello Ally,
happy new year.
unfortunately, some things from the old year have remained the same. The unattached picture-links for example. I read the log file and it seems to be a memory problem. What do you suggest I do? How can I limit the attached files so that I do not reach the limit? Or can I increase the memry?

Thank you and best regards,
ben
