Subject: Unable to save Group Email Account in EspoCRM 9.2.5 - "invalid" error

[Segelwolf]

Environment:

• EspoCRM Version: 9.2.5 (upgraded from 9.1.8)
• Server: all-inkl.de shared hosting (Premium plan with SSH)

Problem Description:

I cannot save a Group Email Account through the Admin UI. Every attempt to save results in an "invalid" error message, regardless of whether I'm creating a new account or editing an existing one.

Steps to Reproduce:

• Administration → Group Email Accounts → Create
• Fill in all required fields:
  • Email Address: wolf@segelwolf.com
  • Name: Wolf Knipfer - der Segelwolf
  • Status: Active
• Configure IMAP tab:
  • Host: w020ba72.kasserver.com
  • Port: 143
  • Security: TLS
  • Username: wolf@segelwolf.com
  • Password: [entered]
  • Monitored Folders: INBOX
• Configure SMTP tab:
  • Host: w020ba72.kasserver.com
  • Port: 587
  • Security: TLS
  • Auth: Enabled
  • Auth Mechanism: LOGIN
  • Username: wolf@segelwolf.com
  • Password: [entered]
  • Shared: Checked
• Click Save

Expected Result: Account should be saved successfully.

Actual Result: Error message "invalid" appears. No further details in the UI.

Browser Console Error:
Uncaught (in promise) invalid

Server Log Error (data/logs/espo-YYYY-MM-DD.log):
[2025-11-28 15:16:40] WARNING: E_WARNING: openssl_decrypt(): IV passed is only 12 bytes long, cipher expects an IV of precisely 16 bytes, padding with \0 [2025-11-28 15:16:40] CRITICAL: (0) OpenSSL decrypt failure. :: POST /Email :: /www/htdocs/w020ba72/crm.segelwolf.com/application/Espo/Core/Utils/Crypt.php(99)

Additional Context:

• SMTP/IMAP connection tests via telnet work perfectly
• The same credentials work in Thunderbird
• Admin user has proper role and team assignments
• This issue persists after:
  • Upgrading from 9.1.8 to 9.2.5
  • Clearing cache
  • Creating proper Admin role and Team
  • Logout/login

Workaround Attempted: Created the account via direct SQL INSERT into inbound_email table, but this causes OpenSSL errors because passwords are stored unencrypted.

Questions:

• Is this a known bug in 9.2.5?
• What is the proper way to create a Group Email Account when the UI is broken?
• How should email account passwords be properly encrypted for direct database insertion?

This issue is blocking me from using EspoCRM's email functionality. Any help would be greatly appreciated.

Definitely this is an issue with your instance. tested this on version 9.2.5 and works fine.

This could be caused cryptKey config - could be corrupted - check that in your config file.
