When setting up Gmail as email-client to send emails through Indichosts.net SMTP servers at Gmail >> Settings >> Accounts and Import >> Send mail as >> Add another email address .
we get following error;Couldn't reach server. Please double check serve and port number.
The recipient server did not accept our requests to connect. Learn more at https://support.google.com/mail/answer/7720 [mail.domain.com xxx.xxx.xx.xxx: unable to read banner], code: 0"Your email server is too slow... failed to respond before timeout.
Gmail is a listed-source of large-volume SPAM emails and when it tries to replay emails through our SMTP server, it is blocked by many 3rd party anti-spam measures in place on SMTP server.
We will have to disable all the anti-spam measures setup on mail-server to enable Gmail to relay email through our SMTP servers. This will result in increase of incoming SPAM to all clients hosted on shared server. The majority of the clients on shared server do-not require Gmail as email client, but prefer to use Webmail or Local email-client (Outlook, Thunderbird etc) or commercial Google Apps (which is 100% compatible with our servers) to manage emails.
If your requirement of using 100% free Gmail as email-client is mandatory, we suggest upgrading your plan to Semi-dedicated (SD-1) so that we can provision a suitable VM with your custom mail-server configuration.
