GDSI — email setup on the new server

For both POP and IMAP — edit the existing account

1. Open Outlook and click File → Account Settings → Account Settings…
2. On the Email tab, select your @gdsi.ie account. The Type column shows POP/SMTP or IMAP/SMTP — note which one you have.
3. Click Change…
4. Set Incoming mail server and Outgoing mail server (SMTP) to mail.your-server.de.
5. Set User Name to your full email address. Leave the password as it is. Tick Remember password.
6. Click More Settings… → Outgoing Server tab → tick My outgoing server (SMTP) requires authentication → choose Use same settings as my incoming mail server.
7. Open the Advanced tab:
   • POP Incoming server (POP3): 995, tick This server requires an encrypted connection (SSL/TLS). Do not change the “Leave a copy of messages on the server” options.
   • IMAP Incoming server (IMAP): 993, encrypted connection: SSL/TLS.
   • Outgoing server (SMTP): 587, encrypted connection: STARTTLS (in older versions it is called TLS).
8. Click OK → Next. If Outlook runs a test, both lines should complete without errors. Click Close → Finish.
9. If Outlook asks for your password, enter your current password and tick Remember my credentials.

POP your folders and old messages stay on your computer exactly as before. IMAP Outlook will refresh your folders from the new server; with a large mailbox this can take a while — leave Outlook open.

Before you start

New Outlook does not let you edit server settings, so here — and only here — the account is removed and added again. This is safe only for IMAP, because your messages are on the server.

1. Open https://webmail.your-server.de, log in with your full email address and password, and check that your folders and messages are there.
2. Make sure you have no unsent drafts that you still need.

IMAP Remove the old account

1. Click the gear icon (Settings, top right) → Accounts → Email accounts.
2. Next to your @gdsi.ie account click Manage → Remove.
3. If Outlook asks where to remove it, choose Remove from this device. Do not choose “Remove from all devices”.

IMAP Add it again with the new settings

1. In the same Email accounts page click Add account.
2. Type your full email address and click Continue.
3. If Outlook offers a provider list, choose IMAP.
4. Enter your password, then click Show more (advanced settings) and fill in:
   • IMAP incoming server: mail.your-server.de, port 993, secure connection SSL/TLS
   • SMTP outgoing server: mail.your-server.de, port 587, secure connection StartTLS
   • User name (incoming and outgoing): your full email address; password: your current password
5. Click Continue. Your folders will appear and fill up over the next few minutes.

If Outlook does not show the server fields or cannot connect, stop and email us — you can keep working in webmail meanwhile.

For both POP and IMAP — edit the existing account

1. Open Outlook. In the menu bar click Outlook → Settings… (on older versions Preferences…) → Accounts.
2. Select your @gdsi.ie account on the left. The account type (POP or IMAP) is shown under the account name.
3. Check User name is your full email address. Leave the password as it is.
4. Incoming server: mail.your-server.de
   • POP port 995, tick Use SSL to connect
   • IMAP port 993, tick Use SSL to connect
5. Outgoing server: mail.your-server.de, port 587, tick Use SSL to connect.
6. Click More Options… under the outgoing server → Authentication: Use Incoming Server Info → OK.
7. Close the Accounts window. If you are asked for your password, enter your current password and choose to save it.

POP your stored messages stay on the Mac. IMAP folders are refreshed from the new server — leave Outlook open for a while.

For both POP and IMAP — edit the existing account

1. Click the ≡ menu (top right) → Account Settings.
2. Under your @gdsi.ie account click Server Settings. Server Type at the top shows POP Mail Server or IMAP Mail Server.
3. Set Server Name to mail.your-server.de. If Thunderbird warns that you are changing the server name, click OK — this warning is expected. (Never accept an SSL/TLS certificate warning.)
4. Set the Port: POP 995   IMAP 993. Connection security SSL/TLS, Authentication method Normal password, User Name your full email address.
5. Click the account name itself (the line above Server Settings). At the bottom, Outgoing Server (SMTP) shows which outgoing server this account uses — remember its name. If you use other email accounts in Thunderbird (not GDSI) and they use this same outgoing server, stop here and write to us.
6. In the left column, at the very bottom, click Outgoing Server (SMTP), select that same server and click Edit…
7. Set Server Name mail.your-server.de, Port 587, Connection security STARTTLS, Authentication method Normal password, User Name your full email address → OK.
8. Close and reopen Thunderbird. If asked for the password, enter your current password and tick Use Password Manager to remember this password.

POP your local folders and old messages stay exactly as they are. IMAP Thunderbird refreshes your folders from the new server — leave it open for a while.

For both POP and IMAP — edit the existing account

1. Open Settings → Apps → Mail → Mail Accounts (on older iOS: Settings → Mail → Accounts).
2. Tap your GDSI account. If you see a line with your email address under IMAP (or Account), tap it to open the account details.
3. Under Incoming Mail Server set Host Name to mail.your-server.de. User Name must be your full email address; leave the password as it is.
4. Under Outgoing Mail Server tap SMTP → tap the primary server (at the top) and set: Host Name mail.your-server.de, User Name your full email address, Password your current password, Use SSL on, Authentication Password, Server Port 587 → Done.
5. Go back to the account details, open Advanced and check: Use SSL on, Authentication Password, Server Port IMAP 993 / POP 995.
6. Tap Done (top right). The iPhone checks the settings — wait until it finishes.

Then open the Mail app and pull down on the Inbox to refresh.

For both POP and IMAP — edit the existing account

1. Open Blue Mail → tap the menu (☰) → Settings → Accounts.
2. Tap your GDSI account → Incoming/Outgoing Settings.
3. Incoming (keep the existing type, IMAP or POP3): server mail.your-server.de, port IMAP 993 / POP 995, security SSL/TLS (never the option that says “accept all certificates” or turns certificate checking off), user name your full email address, password your current password.
4. Outgoing (SMTP): server mail.your-server.de, port 587, security STARTTLS (again, not the “accept all certificates” variant), authentication on, same user name and password.
5. Save the changes. Blue Mail will reconnect; your folders refresh in a few minutes.

Log in

1. Open https://webmail.your-server.de in any browser.
2. On the KONSOLE Webmail login page enter User name: your full email address, Password: your current password. Leave Mode as Automatic, choose your Language and click Login.
3. Bookmark the page. After the move, new messages will no longer arrive in the old webmail.

POP users: webmail only shows messages that are still on the server — the messages already downloaded to your computer stay in your mail program.
