Interactions between email servers and clients are governed by email protocols. The three most common email protocols are POP, IMAP and MAPI. Most email software operates under one of these (and many products support more than one).  The correct protocol must be selected, and correctly configured, if you want your email account to work.

Hey Everyone,
 This started late last week all of the domains we host are unable to send out to AOL but we can receive aol email.
Ive checked all of our domains against blacklist as well as the server IP.

Any ideas on this ? I'm completely lost at this point and still waiting to hear back from AOL.  Is there anything I can check or do to rule things out?
Our mail service is server 2012 running smartermail.

Greetings,
my not-for-profit has 20+ service-focused email accounts for different business needs. Right now I keep about 10 tabs open on my desktop to monitor incoming traffic and reply when needed. Is there an app/dashboard (like Hootsuite) which I could use to create dashboards to manage these Inboxes?

Thanks!

I have a domain a purchased through GoDaddy. I then am using HawkHost to send and receive emails. I changed the MX records accordingly.

For some reason, I can send messages but I can't receive them? Any idea what would cause this? Is there anything other than the MX records I should be changing on GoDaddy?

Also kinda strange... if I do the Outlook "Test Email" the message ends up coming through. That is the only message that makes it into the inbox.

Dear Sir,

We have a software to send bulk emails to our clients which contains the course materials. When sending the bulk emails, there are lots of error/time-out which the destination mail server reject our emails. I've solved the problem for those @gmail.com by adding a record on our DNS server to proof we are not the spammer. But yahoo and hotmail not solved yet. Are they have this mechanism?

Thank you.

With regards,
Wataw

Is there such a list of IP or smtp domains (doesn't have to be up to the hour up-to-date) list so
that we can block at our smtp?

Blocking by firewalls is not good as the emails will still come in

What's the easiest way to move from pop3 to imap on multiple devices?
Pretty sure the mac stuff (iphone, ipad & possibly mac book) are currently using imap, but the PC (desktop & laptop) is the one that makes me nervous. I can envision myself with hundreds, if not thousands of duplicate emails to sort through when its all said & done!

I get an email in outlook 2016 through my pop mail server (if that matters), with the specific email I am looking at sent from gmail... but I think this is a generic question.

On the to line, along with my name, it might show 'steve smith'; 'bob jones'; etc.... the other people it was sent to, with each name in single quotes (this is a group mailing)

Each is a hyperlink - i can hover on a name and a little window pops up with the contact image (just the default outline), and the mail icon is clickable.  A down arrow brings up a bigger contact window with that person's email address.

My question - where is it getting all those person's names?  From the sender's contact list? or is it matching to my contact list? Don't think that's the case, 'cause I don't have some of those people.

and when I send an email, is it also picking up the person's name and including it along with their email?

If I was to have a contact for 'bob (what a butthead) smith'  with email bobsmith@gmail.com, when I type an email to bob smith, does he see that name I have for him!?

Is there a way to keep that from being sent? so he just sees it was sent to bobsmith@gmail.com?

Hi Experts exchange.  I have an application that sends emails upon completing a arduous process.  Ie.. we have to create a permit and inspect it and what not for the email function to fire off from the application.  Our email functionality has been suspect and I was wondering if there was a quick and easy way to send an smtp request to our smtp server from a command line to quickly test functionality without having to create the permit and inspect it.
Does anyone know how to do this.
the server is windows 2012.

if someone could type the syntax or command, that would be awesome.

example variables you could use.   the sendto address is BigDoggy@gmail.com   the smtp server address is 192.168.1.100  the hostname of the server trying to send the email is bigsun with ip address 192.168.1.101

those are fictious settings above but just wanted to be able to tie logic to syntax.
Can someone help me out.

If we have valid SSL cerfiticate for server/client authentication, is there any reason to have a TLS certificate?
Asking because I'm receiving the following event frequently in event viewer

"There is no valid SMTP Transport Layer Security (TLS) certificate for the FQDN of exchangecas.cfwebmasters.com. The existing certificate for that FQDN has expired. The continued use of that FQDN will cause mail flow problems. A new certificate that contains the FQDN of exchangecas.cfwebmasters.com should be installed on this server as soon as possible. You can create a new certificate by using the New-ExchangeCertificate task."

Also should expired certificates be removed?

such as

From: External User <jane@abc.com>

To: Internal User <julia@abc.com>

Reply-To: External User <jane@ourspamfilter.com>

The reply to is appending to our spam filter that we use for incoming and outgoing mail

We have 2 AD sites, Exchange 2013 in each site and different domains in each site but same organization. When user in Site A with domain A send an email to external address plus a user in Site B with domain B, Server transfer the message to Exchange in Site B instead of solving the names and creating two copies of the message, one to transfer to Site B and one to be sent through Sent connector. All send connectors are scooped and we check Exchange servers to make sure they are in different Ad sites. If user in Site A with domain A send message only to external address it goes to the right send connector, the problem only occurs when a user from Site B with domain B is copied in the message.

Any help will be appreciated.

My OS is win 10 pro 64 bit and I have the Office 365 and use Outlook owa.  i managed to switch on Conversations and it is now very convenient as I am able to review the response I sent.  
But sometimes an email is outside the conversation, but it is relevant to that topic.  Is there any way I can lump them to a conversation.  Attached is an example.  i would like to add the email at 6.08 PM to the conversation below with the others.  Thank u for your response

Greetings wise wizards of EE:

I'm helping a friend who has a "premium" Yahoo e-mail account ($20/year or so), that he has used for approximately 20 years. He finally has decided to switch to another provider, due to concerns over security, and is interested in Gmail. He has been using Yahoo web mail all that time, and has hundreds of custom folders on the Yahoo server, along with thousands of messages, all of which he wants to keep. Contact migration seems fairly straight forward based on my research, but not so for custom folders & messages.

Here are my questions:

1. What is the best way to migrate custom folders and messages from Yahoo to Gmail?

2. I assume that the custom folders & messages are COPIED to Gmail, so that the originals will remain on the Yahoo server, yes?

3. Once the migration is complete, my friend doesn't want his old Yahoo account to become a "zombie" account, so what is the best way of deleting/ending his Yahoo account?

4, He has 1,800 contacts... I've heard somewhere in my travels that in terms of e-mailing his contacts with the new address, to avoid spam filters, he should send a mass e-mail message with no more than 50 contacts per message, no more than 100 contacts per hour, no more than 200 per day... is that true, and is there a better way to send a mass e-mail to his contacts that just a standard message?

Any help in this regard would be greatly appreciated.

Many thanks in advance,

Zovoth

How can I tell if a commercial third-party email service provider is an intermediary between the original sender and me?

I'm familiar with "view message source."

I am trying to setup Nagios to monitor SMTP traffic flow for an external domain (One of my clients).

My Goal is to get an alert if SMTP traffic is not passing every so often to their SMTP server.
We had a client who had hosted email through a different solution provider, that inadvertently suspended their account, and they didnt notice it for 5 hours, and were curious why we didnt notice their hosted email solution was not receiving mail.

I am curious if anyone has any information on how to obtain this. I literally just setup nagios for the first time today and believe it can work but am having trouble.

Thanks in advance.
