Using an external SMTP server to send mail via different addresses in Gmail
There is an awesome feature in Gmail that makes it stand out from many other webmails and it’s that you can specify an external SMTP server so that you can send mail from other e-mails. I understand this is an advanced feature that not so many people use but it has a major flaw.
If you change your password on the account that you use to login into your external SMTP server your emails will not be sent. And that is of course fine but the scary part is that you won’t get any form of error or notifications that this happened. Hopefully, Google will fix this soon and give us an error when it can’t log in to the SMTP Server.
