This may be due to some difficulty with the PC's firewall or antivirus.
In case you cannot send emails with your email client, try the following:
1- Try to send an email from webmail by logging into your account from https://webmail.yourdomain.com This way you ensure that the sending system works correctly.
If you were able to send an email from webmail, continue with the following.
2- Change the SMTP email output port. Remember that you can use secure connections to the server through the following ports:
SSL incoming mail port (POP3): 995
SSL incoming mail port (IMAP): 993
SSL outgoing mail port (SMTP): 465
Make sure you connect to the server via: mail.yourdomain.com (replacing yourdomain.com with the real one).
3- Enter the properties of the account(s) in question - advanced options - "Server timeout" and increase the wait time to, for example, 4 minutes (by default it is 1).
4- Check, in the email account configuration, that you have the "My server requires authentication" option activated. This configuration is essential for sending emails through the SMTP server.
If, despite these recommendations, you are still unable to send emails from your email client, contact us via support ticket, from your customer area to find a solution to your problem.
