Mail::AddressList can not parse error when S/MIME or PGP integration is active

[ChibangLW]

Used Zammad Version

6.3

Environment

• Installation method: package
• Operating system (if you're unsure: cat /etc/os-release ): ubuntu 22.04
• Database + version: postgresql 15
• Elasticsearch version: 7.17
• Browser + version: [e.g. chrome 83, safari 14, firefox 105]

Actual behaviour

When creating a ticket and selecting a customer, an error message is displayed.

Mail::AddressList can not parse |max.musterman@example.de,Max Mustermann|: Only able to parse up to "max.musterman@example.de,Max Mustermann"

The corresponding production.log shows this error:

RROR -- : Mail::AddressList can not parse |max.musterman@example.de,Max Mustermann|: Only able to parse up to "max.musterman@example.de,Max Mustermann" (Mail::Field::IncompleteParseError)

If the S/MIME integration is disabled the error does not show. It looks like the error does not impact the functionality but seeing a 500 Server Error every time you input a customer is not good.

Expected behaviour

Just input the customer and no error popup displayed.

Steps to reproduce the behaviour

1. Enable S/MIME integration
2. Create new outbound mail ticket
3. Select customer
4. Error message is displayed

It could be related to #5166.
