I use Google Workspace to send emails. Is the IP address I see when pinging smtp.gmail.com the same IP as everyone else?
Secondly, does this IP address ever change?

I am running Postfix MTA on my home server to send bulk emails.I have setup MX records and DNS but rDNS still needs to be configured as gmail etc. won't accept email from my IP. I don't have a VPS so I can't use cPanel or WHM. Is there any other alternative.
NOTE: I can't use a mail provider like gmail as I need to send more than 500 emails daily.
Thanks a lot!
Reverse IP address is linked with the PTR record set by the owner of the IP address which is mostly your ISP. You need to check with your ISP (Internet Service Provider) on updating the PTR record for the IP address assigned to you.
I have a similar problem. My first network had a IP address range 192.168.1.xx and my freepbx server had 192.168.1.2
However now I need to move to a new network which has IP address in the range 192.168.2.xx and my freepbx server had 192.168.2.2
Now if I try to login to my freepbx server connected to the new network, the login always fails. Can anyhow help how to ensure freepbx/freeswitch will work on the new ip address?
thanks, -Anish
The users are per domain in FusionPBX. If you don't login with "user#192.168.1.2" then it will default to domain 192.168.2.2 that you use to access the website.
Once you have logged in you can edit the domain to change it's name. Also check for the old IP address in the variables.
For example, how can I find the IP address of the mail server #yahoo.com or #hotmail.com?
Is there a way to do this on terminal?
Thank you.
EDIT: I meant to say IP address of the mail server dealing email addresses ending with #yahoo.com or #hotmail.com
nslookup is what you're after, or dig. Since you want a mail server you'll want to add the option '-type=mx' (Mail eXchange).
nslookup -type=mx gmail.com
First find the mailserver (might be multiples):
dig yahoo.com mx
Then request the IPv4 record:
dig <yahoo-mx> a
In some cases you can find the IP inside the SPF record:
dig <yahoo-mx> txt
I need a IM client that support yahoo and allow user to set yahoo IM server address.
Yahoo IM servers names (scs.msg.yahoo.com, scsa.msg.yahoo.com, scsb.msg.yahoo.com, scsc.msg.yahoo.com) are not accesible through my company LAN, so I should use IP addresses of their servers.
We can find ip of a domain name by simply pinging that domain name.
My problem was related to another network issue (port 443 was blocked) but initially I supposed that it relates to server ip address.
How can I email to a domain whose SMTP server does not listen on the standard port 25? I need to email to it through webmail, like GMail.
I thought this would work:
user#domain.com:port
You can't do it with gmail. You need to configure a mail server to do this, and it's hard. The only other option is using a firewall to redirect traffic from 25 to your port.
(And this probably belongs on serverfault).
