Robot gets stuck on mail activity

Hi @hLien ,

I faced the issue with the Zoho mail account which we were using for our project. The SMTP mail activity gets stuck without timing out. We found the issue to be linked with the Email sending limits of the particular mailbox. Usually, our mailboxes are not designed for sending unlimited number of mails and after the limit has exceeded the SMTP and IMAP services will be blocked on the particular machine which was sending an exceeding number of mails. Sometimes restart works because it reconfigures something in our machine and the block is lifted. Restart option stopped working for us a while ago, So we had to switch to a more permanant solution.

We started using Amazon SES(Simple Email Service) to send mails, you can configure your Mailbox with SES to send SMTP mails. It is designed to scale Mail communication and is very effective when it comes to using BOTs.

I know this is a very old post, hoping this would help someone in need.

Regards,
Alen Mathew
