Error Could not store sent email

[JanBab]

Hi,
What does this error mean and how do I fix it?
[2025-02-24 08:42:05] ERROR: Email sending: Could not store sent email (Email Account 5e78cddb0821c54f2): cannot send literal string.
We have EspoCRM 9.0.4.
Thanks

Hi JanBab,

Please tell me if this error is repeated for all sent emails in the system? Do problems only occur with this email account (ID 5e78cddb0821c54f2)?

This only happens with two accounts. And it seems that for all the emails of these accounts.

JanBab,

How are these problematic email accounts different from other email accounts? Have you had problems with these email accounts before, or have you just recently added them to the instance?

[JanBab]

I don't see any differences in the accounts from other accounts. The accounts have existed from the beginning. There are also errors in the earlier logs.

JanBab,

Can you please check if the Test Connection in IMAP and Send Test Email in SMTP of email accounts are working properly?

You can also provide screenshots of SMTP and IMAP settings of email accounts in the EspoCRM instance, blurring the email addresses, so that we can check in more detail what the problem might be.
