Error parsing bounce messages

[wedi]

Hi!

I am experiencing errors while importing my logs. Attached you find the output of the cron runner and the log lines corresponding to the mentioned message ids.

It looks like the parser is stumbling on empty envelope senders which frequently occur on bounce messages.

I selected one occurence but I can provide more examples should you need them.

Thank you for looking into this.
