Description Axel Braun 2023-01-30 10:27:02 UTC 
Umlauts in Domains (like Düsseldorf instead of Duesseldorf) are permited since a couple of years.
When sending a mail to one of those domains using mailmerge, LO dumps:

<class 'UnicodeEncodeError'>: 'ascii' codec can't encode character '\xfc' in position 20: ordinal not in range(128), traceback follows
  File "/usr/lib64/libreoffice/program/mailmerge.py", line 262, in sendMailMessage
    self.server.sendmail(sendermail, truerecipients, msg.as_string())
  File "/usr/lib64/python3.10/smtplib.py", line 892, in sendmail
    (code, resp) = self.rcpt(each, rcpt_options)
  File "/usr/lib64/python3.10/smtplib.py", line 553, in rcpt
    self.putcmd("rcpt", "TO:%s%s" % (quoteaddr(recip), optionlist))
  File "/usr/lib64/python3.10/smtplib.py", line 378, in putcmd
    self.send(f'{s}{CRLF}')
  File "/usr/lib64/python3.10/smtplib.py", line 357, in send
    s = s.encode(self.command_encoding)
Comment 1 Stéphane Guillou (stragu) 2023-02-01 13:39:00 UTC 
Thank you, Axel.

I can reproduce with:

Version: 7.4.5.1 / LibreOffice Community
Build ID: 9c0871452b3918c1019dde9bfac75448afc4b57f
CPU threads: 8; OS: Linux 5.15; UI render: default; VCL: gtk3
Locale: en-AU (en_AU.UTF-8); UI: en-US
Calc: threaded

I also get the "Emails could not be sent" error dialog with:

<class 'UnicodeEncodeError'>: 'ascii' codec can't encode character '\xfc' in position 22: ordinal not in range(128), traceback follows
  File "/opt/libreoffice7.4/program/mailmerge.py", line 262, in sendMailMessage
    self.server.sendmail(sendermail, truerecipients, msg.as_string())
  File "/opt/libreoffice7.4/program/python-core-3.8.16/lib/smtplib.py", line 890, in sendmail
    (code, resp) = self.rcpt(each, rcpt_options)
  File "/opt/libreoffice7.4/program/python-core-3.8.16/lib/smtplib.py", line 551, in rcpt
    self.putcmd("rcpt", "TO:%s%s" % (quoteaddr(recip), optionlist))
  File "/opt/libreoffice7.4/program/python-core-3.8.16/lib/smtplib.py", line 376, in putcmd
    self.send(f'{s}{CRLF}')
  File "/opt/libreoffice7.4/program/python-core-3.8.16/lib/smtplib.py", line 355, in send
    s = s.encode(self.command_encoding)
