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.

Why does a signature need to be hosted?

I have an image of my business card I configured as a signature image with Thunderbird.

I send out emails to my other email accounts, and the image shows up fine. So, what is the reason I need to host the image?

I guess if someone has images blocked, they will not see it. So in that case, would they need to click a URL in order to see the image?

If so, I imagine this enables the recipient to select which image to view versus viewing them all?

I am trying to understand the value of hosting my signature image.

Please let me know.

Hello Experts

I have a client with a .pst file that is more than bursting at the seams.  His OS is Windows 7 so I can install Live Mail, but that's only good until Windows 7 goes away.  So I've opted for Thunderbird.  But I'm not finding good information about importing his email.

I guess another possibility is to use Live Mail for now and see how it converts with the mail program in Windows 10.  Has anyone made that transition?


Please provide me with the steps on how to export Outlook 2016 contacts into an online Gmail account.
Emails from Mac are having fonts changed randomly. One user is complaining that everything seems okay on his Mac, however, he noticed that when people reply to his emails, his [art has different font and size to the one he used to send that email. We did some testing and it is definitely his machine. He is using Outlook 2011 for Mac and Mail. He has Mac OS X version 10.10.5. We are using Office 366 and he has Exchange account added to his email programs.
I was thinking about disabling Rich Text options on the email server and only leaving Plain Text and HTML.

How can I make sure that his emails look all the same?

We have this script to delete phising emails from our organisation, however we also these requirements:

1)      We need to add into the search-mailbox after -searchquery an additional requirement for date or time, as we only want to search for emails since a certain date. We use this script to delete phishing attack emails, so we know when they started, so need to be able to search for all emails since a date and delete them if the subject matches. So the most recent example, would be all emails containing subject “RE: NOTICE: MC Support UPGRADE.” however only emails received after 01/03/2018. I assume we can just do -searchquery “Subject:’Content of Subject’ AND ReceivedDate:>01/03/2018” or something like that?
2)      We need to be able to search for subjects with special characters in. –searchquery “Subject:’RE: NOTICE: MC Support UPGRADE.’ Will currently give an error as it won’t like the : in the subject.
3)      We need to be able to search for the above criteria, but also potentially include only emails from certain email addresses. One of the phishing emails was “RE: Attention (Staff Migration)” which could be very close to something we actually send to users. The phishing email only came from a certain email though, so if we add an extra criteria for sender, that would help us focus the search.

Please can someone show me how to achieve this?

also I would appreciate if you any other suggestions for improvement.

My boss has a new iPhone8. I've set him up to access the IMAP server at the office. Inbox works just fine and he can send messages. The problem is that the Sent and Trash folder on the iPhone do no synchronize with the server. Apparently, this is not an uncommon problem since I've found lots of posts about it. However, none of the instructions I've found so far seem to work. How do I do this?

The mail server is Dovecot IMAP. The iPhone is using the normal mail facility, nothing special or 3rd party. The selected server setup is 'Other'. Inbox synchronization works. Messages deleted on the iPhone, and sent messages are not synchronized with the corresponding folders on the IMAP server.
I have an e-mail under our company website.   But after a few issues the website is going to be moved to a new server.  Supposedly all our e-mails will be deleted.   I need to get all my thousands of e-mails downloaded to my outlook on my computer before this happens.  But I cannot figure out how to do this.   What do I have to do to get my folders of e-mails from the website server to my outlook?   I am running Windows 7 with Office 2010.
The user has tens of thousands of past gmail messages.  They appear to be in "All Mail" folder in gmail.    Gmail will delete about 100 at a time.

Is there a way to delete a larger amount?

The  Mail  Application on the Mac keeps trying to synchronize them, which slows down the computer.

User has iPhone, iPad and Dell Windows 10 with Outlook 2016.
The three devices are not synchronizing deleted emails properly.
They have Comcast email which shows IMAP setup on all three devices.

If they delete from iPad, message is removed from Outlook but not iPhone
If they delete from iPhone, message is removed from Outlook but not iPad
If they delete from Outlook, message is not removed from either iPhone or iPad

What should I check?   Thanks.

How can I disable the Gmail email account security alerts?

An organization I am consulting for had their Veeam backup email alerts setup using a single Gmail email account that accesses this Gmail account using the SMTP email protocol.

The Veeam backup program on 40 Windows computers sends alerts to this Gmail email address everytime that the Veeam backup succeeds, fails, or has any issues.

These users often travel with their laptops and I am constantly receiving Gmail security alerts related to this email account.

So is there any way that I can disable the Gmail email account security alerts for this Gmail email account?
Any suggestions for an offline email reader client? I tried Postbox (a paid for product), and it does not function properly for offline email reading as it is a very buggy product. It works as expected for online email, but nothing good to say about offline. Thank you in advance.

Is there any way of exporting corporate Gmail email accounts to .PST files without having to setup the account with Outlook first and then exporting the email accout to a .PST file?

I need to export an entire organization's corporate Gmail accounts to .PST files and am looking for the easiest ways of doing this.
My wife had her Gmail account hacked some time ago. Google admin shut down the account for a couple weeks before reinstating it. They restored the account after she proved it was her account.

When her account was restored though, it now forces 95% all incoming mail to the "trash" even though it is from trusted emails and replies to her emails.  She uses Safari browser.
Drafts folder locks up Outlook.

I have a Windows 10 user whose Outlook 2010 locks up if he tries to open his Drafts folder.  If he stays out of Drafts, he's fine.  There is one item in the drafts foder which I figured is the culprit.  Trouble is when I go into thie users mailbox on a different computer to try and delete the item, it also locks up there as well.  Is it a bad item?  Or something else?  and if so, how do I delete it?

Thanks for your help.

Hi -

I have a client who recently had their Apple mail app crash and i needed to update to High Sierra to sort it because the mail folders had got too large to make it worthwhile to do a Time Machine restore.
The client now has all email accounts back but the messages only go back to last week (despite being on IMAP i dont think it was set to save much on the server).
They have asked if i can restore the emails from 2017 from some of the archives that were made at the end of 2017.
I did not make the archives so i had to search for them. I found a folder with the heading archives 2017 but the folders are several, totaling to 22GB but the one folder called archive.mbox is only 2 GB. The largest one i could find has a long name which does not initially make any sense. I have attached a screenshot.
I have initiated an  import of the folder but being being so large i will have to wait a while before i know if it is the correct one. Could someone explain to me why these folders are created and named in such a way if the secretary who did the archive i assume followed the correct procedure. Why isn't there just one MBOX file?

I was wondering if it is possible to place a limit in outlook within a single meeting request to only one room. Specifically, not allowing users to book two or more rooms with one meeting invite.”
Good Afternoon Experts.

A user received an email with a threat.  I looked at the headers on the original email, but I'm a little puzzled as who the sender is.
Can anyone help me figure out the sending ISP or domain name?
As it looks like the sender is from, which I changed from my actual domain name, but how would that be possible?

I host the e-mail for on Exchange 2010.  The client is wanting to forward this mail to which is being hosted by another company.  I cannot find a solution specific to this situation.

Please advise.

Thank you,

On an iphone that's being retired. Wife had pop account.  So sent mail from the phone is only on the iphone in the sent folder.  Doesn't come off with backups, right?

She wants to save those sent emails.

I was looking at 1 way - setup icloud email account on the phone. then i go into the pop account's sent folder.  chose edit, check 1 then move... choose the icloud inbox and it seems to go (graphic shows it dropping into that folder).  And it is not in the sent folder of the pop account anymore.

But it doesn't show in icloud account.

What am I doing wrong?  Is there a way to get those sent items back into the pop sent account?

Another way to do it?

i tried ifunbox but couldn't find mail folders.
