Question Email accounts IMAP and POP3

[brainstuffch]

Is it possible that PLESK only allows either IMAP or POP3 for email accounts and that it is not possible to have both IMAP and POP3 accounts in Thunderbird?

If you have set up an IMAP account in Thunderbird and then try to set up a POP3 account for the gleice email address, then an error message appears (wrong password) although the credentials are completely correct.

 

[Peter Debik]

The server allows concurrent connections by IMAP and POP3. Whether it is possible in Thunderbird to allow IMAP and POP3 at the same time for the same mailbox: I'd say yes, but I have never tested it, because I never had a case where this could have been useful.

If "wrong password" is displayed, there is some likelihood that the system is right and that the password needs to be reviewed.

 

[brainstuffch]

If we try to set up a pop3 account in Thunderbird this fails with wrong password. But the password is not wrong. It is not possible to find out if the problem is on te side of PLESK or on the side of Thunderbird.

And if you had never a case where this could have been usefuul, you are not a professional user of IMAP trough TB.

There are a lot of verry stupid issues in the IMAP protocoll.

-- the server can be out of space due to a full junk or trash folders
-- you can not store a lot of archive files
-- if you have a lot of high usage accounts ... TB will take a lot of time to download the headers ...
-- if you do not delete, every day, all the files in the incomming mail folder, you will have at the end of the month hundereds of files in this folder.

The only way to handle this is, to have at least one computer where you install for each mail-account a IMAP and an POP3 Account. On the IMAP account you will see and handle all the Mails from the last xx Days.

And some times you download all files from the server with POP3 who will then have filtres to copy all identified files in specific folders for archive issues. The POP3 account can download all files and he can delete only all files not older then X Days. In this way the the access to the IMAP Server will not have problems due to thausends of old headers. And also the POP3 account will store at one place all the archive files.
We have als a little feature in our box who will increase the IMAP mail ... and we have also developped a system who will provide reliable, SPAM free email. This will save at least 75 millions of €/DAY to our econnomy in Europe. (this is our version, since Bill Gates we waste abaut 10 times more money EVERY DAY with Spam.

Since abaut 50 years, we have not any reliable electronic communicationssystem. 1970 we have replaced the reliable TELEX by fax and other stupid bull ****. And we have destroy the E-Mail with stupid Filters, SPAM, Scam, PISHING and other stupid time wasting games.

The developpers of IMAP was verry stupide ... they do not have do that her system will provide an extremely reliable messenger.

We need a verry reliable telecom System with a button who we can change from "ultra serious and all partners identified" to "stupid tweet for stupid people".

Please ask the developpers of PLESK if there is a way to accept that IMAP and POP 3 will work together in one account.

And ask the developpers of PLESK to get in touch with us: we need a very little enhancement in the mail server system who will made that we receive all needed mail without SPAM, SCAM and other not needed stuff. E-Mail must replace the fax and enhance the other non sense bullshit. Email must become an reliable add-on to an instant messenger.

IMAP and POP3 are just two protocols by which you can access a mailbox on the server. Both are supported by Dovecot, the "mailbox server" on the server. It may not be possible to query the same mails at the same time through two different protocols from the same source due to file locks, but Thunderbird does not do that anyway. It is for sure possible to access the same mailbox through IMAP and POP3. The credentials are the same. There are no differences in password handling.

Have you already searched the /var/log/maillog for "failed mail authentication attempt for user 'youruser@yourdomain'"?

@Peter

We think that the problem is on the side of Thunderbird .... do to the fact, that it is possible to get e-mails by pop3 when we use an other computer or an other Thunderbird profile, we think that Thunderbird will not accept IMAP and POP in one profile for the same e-mail account.

We have tested to try this on 2 computers in the same time and we can use both protocols.

The fact that TB says that the password is wrong is a bug. TB will only not that we install 2 times the same account.

The people from the TB Forums has tried to say to us, that we are crazy if we install one account as pop3 and IMAP but they do not say if this is possible or not.

It seems also, that we are the only users who do not use the e-mail only for "Twitter-messages" and other unserious issues.

Still in the beginning of the IMAP protocoll we have stated that there are a lot of very stupid bugs in the IMAP system.

We accept only since about 5 Years that our customers use IMAP insteat of POP3. But this was not a good idea.

The problem is simple: when the server space is not illimited ... IMAP will get in problems due to occupied by SPAM, the Trash space, and the backup. A second issue is the fact, that IMAP download constantely all headers and mails but do not store thease Files on te local Thunderbird.

This will mean, that every time you open Thunderbird, TB must download a lot of things but do not store these Datas. If you want to store the datas, you must download all at new....

If you have a lot of accounts with a lot of e-mails, you must often wait a long time.

For this reasons we had tested a new system of handling: we have set up in the IMAP account filters who move the needed Emails automatically down in local folders.

This works some tiime fine ... the needet mails are moved down in a local folder but if we do not delete every day all the SPAM and not very interesting mails ... we have after x months accounts with xxxxx Mails in the inbox. Often the SPAM Folder is full, it is possible that the SPAM folder is hidden ... An other problem is, that mails needed to accept passwords, comes on the local folder in a false folder and we do not find thease mails ...

For these reasons we had the Idea, that we will create also a pop3 account in TB who will download all the mails older then 10 days.

And this will not work. Probably it will be possible to create a second TB Profile with the POP Version of the accounts ... but this will then create a problem with the files still mouved to the local folders in the IMAP instance.

Now I have fund a new idea: I have set-up a filter ... move all e-mails older then 10 Days in a local folder and an other filter move mails marked with as download also to the local folder. In this way only mails < 10 days stays on the IMAP and the older mails will be on the local computer. (the "local computer" is a Cloud and in this way the TB Files will be accessible from all locations ... on some computers it is also possible to use only local mail clients.

I’m running into the exact same issue as well. I have an IMAP account already configured in Thunderbird, and when I try to add the same email address as POP3, I also get the “wrong password” error even though the credentials are correct. It does make me wonder if Plesk restricts an email account to either IMAP or POP3 at a time. Glad to see I’m not the only one facing this—would be interesting to know if there’s an official limitation or workaround. Sorry for reviving an old thread, I want suggestions.

And we also ask the developers of PLESK to get in touch with us. We need a very small but important enhancement in the mail server system that ensures we receive only the emails that truly matter—free from spam, scams, and unnecessary noise. Just as a Morse code translator filters raw signals into clear, meaningful messages, modern email systems should intelligently separate real communication from digital clutter. You can check here for more. Email must fully replace outdated tools like fax and evolve into a reliable, trusted add-on to instant messaging rather than being overwhelmed by nonsense and abuse.

Is there anyone who can guide me?

@emilyy3 Plesk does not restrict email accounts to either IMAP or POP3. The user who initially reported the issue mentioned that the same is related to Thunderbird. Have you tried testing the scenario with another email client?
