Connection IPs for IMAP / SMTP Logins

[powermix]

When you sign in using IMAP / SMTP credentials to an email account (Google, Yahoo, Outlook etc.)

What is the connection IP? Is it your local IP or the IP from those services?

Let's say that you add your Gmail account to the Thunderbird client.

In Google's eye, what would be the connection IP of that login?

Which ever triggers the SMTP to auth it can be your local ip or Thunderbird or vpn or proxy same for any SMTP.

In that case, will the ESP find it suspicious if multiple accounts log in from the same IP (using SMTP)?

Logging in via browser will trigger something on their systems, but not sure if the log in is done via SMTP.

Exactly for that is the reason most of the bots which are built has proxy support to avoid this kind of issues. Trigger ping is easily traceable from SMTP so use rotation proxy.

Good Luck

Thanks for the tips! I thought that if you log in using SMTP, the IP would not be taken into account.

Another question I have...

If I click in a link inside an email via IMAP, does this click get tracked somehow by the ESP? (I think it can't be tracked)

I know that if you click in a link inside an email in the web interface, this click gets tracked by ESPs (Gmail, Outlook, Hotmail).

That way they can detect spammy links an so on.

The Proxies are not the problem. So mostly everything that @xcodes mention is true. But he missed very important problem there! The proxies MUST have the port restriction lifted for 993 imap and 25 smtp.
