Email Clients





An email client, email reader or more formally mail user agent (MUA) is a computer program in the category of groupware environments used to access and manage a user's email. A web application that provides message management, composition, and reception functions may internally act as an email client; as a whole, it is commonly referred to as webmail. Likewise, email client may be referred to a piece of computer hardware or software whose primary or most visible role is to work as an email client. Email clients can also have other systems, like calendars, notes and contact managers.

HI Folks,

I wonder are there any experts out there that know how to analyse email header source. One of our clients received a bogus email that appeared to come from one of our staff members email address.. it did not. .. unless his email account was compromised.

I've asked the receive to send me the header of that bad email and they did. I put the message header into a Google Product called "Message Header Analyzer" and the results are attached.

My question: from this is there any way to determine the source of the email? Our domain is So did the come directly from us or is it from another source and just looks like from

Am I making sense here? Any help would sure be appreciated!

I need to migrate >50 users from certain web hosting service to a dedicated server with Zimbra Open Source Edition.
I do have plaintext password for all users.
They all use some Microsoft Outlook version (2007, 2010, 2013). Most of them use POP3, and they want to switch to IMAP in order to have all contents in sync between different devices (computer, webmail, smartphone).
I cannot migrate all users at the same time: I need to do this for 4/5 users each day (I will personally re-configure email clients, smartphone).
I need some suggestion to manage PST import (in some case, one single user could have 3/4 PST files, > 10 GB).
I would like to manage this migration very smooth, possibly without stopping users for a long time.
Any suggestion?
Thank you!
Outlook 2016 - Not sending reported error (0x800CCC1A).
Have a client which cannot send emails using IMAP account via the SMTP connector.

Have run Scanpst.exe and repaired the PST and OST files, have run SFC /Scannow and created new profiles but each time trying to send out emails gets the attached error message and the emails don't send, just stuck in Outbox.  I have also completely removed Office from the PC and reinstalled fresh after restarting the PC and still fails to send emails with the same attached error message!
I have now installed eM Client (trial) and configured as the same account/ server settings etc... and the email account is working sending emails fine within eM client email client so this is showing it's an issue with Outlook 2016 itself.

The OS on the PC is Windows 7 but this isn't the issue as clearly working using eM client.

Any ideas to why Outlook 2016 is causing this issue?
The user would like to send out a text message to a group of phone numbers.
A quick look on the web brought up
There's a $10 monthly and a 45 cent per-message fee, but they are entitled to be reimbursed for their services.

Is there some software that could send out group texts that might be cheaper?

I am using Office 2016 provided by Office 365. Since about 30 days ago when I try and search my Outlook inbox it attempts to for about 15-20 seconds and then prompts me with a message saying "We're having trouble fetching results from the server..." and it gives me an option to "Search in emailed stored on this computer" which when clicked shows me email stored in my local inbox. It's becoming a waste of time.

I originally ruled out a .OST corruption issue when I realized it was happening on my laptop and my desktop. However I still went through the steps to compact and repair my .OST, re-index my Outlook, delete and remake the profile. The issue is still there.

Any ideas?

How can I download my HOTMAIL messages inbox, sent and drafts onto my PC?
I am needing a revolving server system that changes IP address once it starts getting hits from sever filters. It needs to be seamless and use the same email address that we establish to send emails out from, but configures a different IP with every 50 to 100 emails. This is what we need to get a marketing job done and the email messages we want to send have to fit the character count specifics and font type. The subject line is the most important and the size cannot exceed X kilobytes for the total email to reach target market.

Hi - I've been asked by a friend to assist them with an issue. They were having problems with Windows 10 and contacted a company who appears to have 'Reset' the PC within the Windows 10 recovery settings. At first glance, it seemed that all the installed applications and locally held data (word docs, photo's etc) had been removed. I'm sure you will not be surprised to hear that there is no backup. However, a copy of the user profile (including data) has been located within the 'windows.old' folder. This is great news for my friend. The issue that I would like assistance with is as follows:

1) They were using Windows Live Mail to access\download their email. This data appears under C:\Windows.old\Users\yourlogonname\AppData\Local\Microsoft\Windows Live Mail.
a) I'm struggling to download a genuine copy of Windows Live Mail - Is it still possible to download from a reputable source?
b) If I can download and install, how do I recover the data into the recently installed Windows Live Mail application?
c) If it's not possible to download, can the old data be imported into another program to view the email? If this is possible, how do I do it?
d) Friend does not remember email password. Original email provider has been taken over a number of times and current provider is unable to verify security requirement to reset password. Is there a tool to recover a password stored in Windows Live Mail that is no longer installed but records exist under windows.old ?

2) Friend is …
We are having extreme difficulties sending outbound email. Whoever solves this will be worth a ton. We have simple email hosted by Network Solutions - 3 email boxes. We use Outlook and IMAP for inbound and SMTP with Outgoing server authentication to send mail. We can use Ports 993 and 143 for IMAP and 2525 or 587 for Outbound email. port 465 SSL or TLS does not work. Ports 110 or 995 work for POP. The Internet provider was ATT - a 2 MB account with 2 static public IPs.
Long story:  After working fine for 2 years, about 2 months ago something happened and we could no longer send email. If we changed the public IP to the second one, then email would flow just fine for about an hour. When it works, we can successfully telnet to ports 2525, 587, 110, 993, 143 at netsol. Then after about an hour we have to change our firewall to use the second static IP, then change back after another hour, etc, over and over. When email quits flowing, the Internet stops also, so we cannot browse either until we change the static public IP.
1 week ago we changed Internet provider to Spectrum 25 Mb account with 5 usable static IPs. Same thing, except Internet always works and mail always flow in. But we have to cycle through to the next public IP every 30 minutes or hour to send email outbound. The available IPs seem to "clear" during that 30 minutes, even the most recently used IP.  I have called Network Solutions multiple times for hours and it is "not their problem" and they will not help …
Has anyone got any recommendations for an FTP client which supports TLS/SSL (not SFTP,) can be automated and can notify via email the log from a download?
I recently updated to outlook 2013 from 2010. in 2010 when I entered text in the search field it only showed the emails received, but in 2013 it also shows matching email from the send emails, is there a setting I can set to only show results from received emails?

Dear Expert, please help
I’m trying to share outlook contacts with delegates, but there are some private notes for each contact. Would it be possible to share and not show notes?
my customer send a bank details change notification to a supplier. by the time that email reached the inbox of the supplier the content and the bank details have been changed.
subsequently the supplier paid the invoice to the wrong bank account
I cant work out how the email could have been intercepted, the pdf attachment with the bank detail notification changed and send to the supplier.
I changed all relevant passwords for email, accounts and so on, i also scanned the desktop for any malware or virus and none have been found.
further testing revealed that the supplier email was unable to receive any emails for my customer, they just never arrived.
I'm at a loss to understand how this is possible and how to prevent in the future. This is now the second time this happened to different customer.
We want to be alerted of conflict of date by Outlook when the user is creating the meeting and hits 'Save and Close'.  Whats the best way to go about it.

I have a ticket on Microsoft about my Symantec SMG (anti-spam) is receiving the  "451 4.7.500 server busy" from (Hybrid exchange 2010 / Office365 -and Postfix for some days) when I try to send a email to (my send connector send to SMG. It has to be this way, and it was working until two days ago).

This question is the same point:

The Accepted Solution is:
"We were being throttled by addresses.  Exchange was trying to send the health check emails outside.  Fixed that and now everything goes through fine."

what does "Exchange was trying to send the health check emails outside.  Fixed that and now everything goes through fine" mean?
With this Configuration
I get this issue in hMailServer. Why?

As per my screenshot (attached), one of my Gmail accounts keeps show as 4 unread messages for about 5 seconds, and then it changes back to 0... or if I actually have 2 unread messages, it will show as 6, etc... then back to the 2 (the real unread number).

- it doesn't happen any of my other Gmail accounts
- it only happens on my iPhone and not on Mac Mail or Gmail in web view
- i've deleted the Mail account and re-added it... but the problem still persists
- i went into the account on my iPhone and selected all emails... marked them all as unread... then selected all again and marked them as read... but the problem still persists

Any help at all would be much appreciated.
