How to continue execution after traceback error

sometime i got

Traceback '(most recent call last):
  File "main.py", line 45, in <module>
    server.sendmail(sender, receiver, msg.as_string())
  File "/nix/store/2vm88xw7513h9pyjyafw32cps51b0ia1-python3-3.8.12/lib/python3.8/smtplib.py", line 899, in sendmail
    raise SMTPRecipientsRefused(senderrs)
smtplib.SMTPRecipientsRefused: {'example@gmail.com': (550, b'The mail server could not deliver mail to example@gmail.com.  The account\nor domain may not exist, they may be blacklisted, or missing the proper dns\nentries.')}'

and script get stopped
i need to know if there solution to continue after any error

with smtplib.SMTP(smtpsv, port) as server:

server.starttls() # Secure the connection

server.login(user, password)
server.sendmail(sender, receiver, msg.as_string())
print(" + {}: {} sent succeffully".format(count, line.strip()))

>Solution :

You can implement try/except to handle error without breaking the flow,

import traceback
try:
    with smtplib.SMTP(smtpsv, port) as server:
        server.starttls() # Secure the connection

        server.login(user, password)
        server.sendmail(sender, receiver, msg.as_string())
        print(" + {}: {} sent succeffully".format(count, line.strip()))
except Exception:
    print(traceback.print_exc())
