Unable to parse Umlaute


Expected behavior:

  • No errors in scheduler_out.log.

Actual behavior:

  • scheduler_out.log

Steps to reproduce the behavior:

  • scheduler_out.log shows several entries where it stumbles upon German Umlaute, e.g.:
    Mail::AddressList can not parse |“Martin Müstermann” martin.muestermann@example.com|
    Reason was: Only able to parse up to "Martin M

This seems to be new in 2.6

Can you please provide the full header of the mail druncated? :slight_smile:

Here is one (anonymized) example with Cyrillic letters, which could only be parsed to the first letter:
