Can I Use a POP3 or IMAP Mail Client With Infosaic?

Short answer: Yes. Microsoft Outlook, Mozilla Thunderbird, Apple Mail, the built-in mail app on any phone, or any other POP3 or IMAP client will send and receive using your Infosaic mailbox. Use mail.infosaic.com for both incoming and outgoing, and remember that outgoing authentication is always required.

Webmail is convenient and there is nothing wrong with using it, but most people eventually want their mail in a proper program — alongside their calendar, available offline, and searchable years back.

Any mail client that speaks POP3 or IMAP will work. There is no special Infosaic software to install and nothing to buy.


POP3 or IMAP — which to choose

This choice matters more than which program you use.

  • IMAP keeps the mail on the server and shows you the same mailbox everywhere. Read something on your phone and it shows as read on your laptop. This is what you want if you use more than one device — which is almost everyone. It also means your mail counts against your server storage quota.
  • POP3 downloads the mail to one computer and, in its usual configuration, removes it from the server. That keeps you comfortably inside your storage allowance, but the mail then exists only on that machine.

If you are choosing today, choose IMAP unless you specifically want everything pulled down to one computer — which is a reasonable choice if your mailbox is large and your allowance is not.


What to use

On a computer, the mainstream options are Microsoft Outlook, Mozilla Thunderbird (free) and Apple Mail on a Mac. Any of them handles POP3 and IMAP.

On a phone or tablet, the mail app that came with the device works perfectly well and is the simplest thing to set up. If you would rather use something else, any mail app from your app store that supports IMAP will connect.

What matters is not the program but the settings, which are the same in all of them.

Set up webmail first and confirm the mailbox works before configuring a program. If webmail signs in, the account and password are right, and any problem is in the client settings — which halves the things to check.


The settings you will be asked for

  • Incoming server — mail.infosaic.com
  • Outgoing server (SMTP) — mail.infosaic.com
  • User name — your full email address, not just the part before the @
  • Secure ports — SMTP 465, POP3 995, IMAP 993
  • Non-secure outgoing — port 25, or the alternative port 8383 if 25 is blocked
  • Outgoing authentication — always required

That last one causes more support tickets than everything else combined. If mail arrives but will not send, it is almost always because outgoing authentication has not been ticked. VPS and dedicated customers running their own mail use mail.YOURDOMAIN.com instead.


Questions and answers

What server settings do I use?

mail.infosaic.com for both incoming and outgoing, with your full email address as the user name.

SMTP 465, POP3 995 and IMAP 993 for secure connections. Non-secure outgoing is port 25, or 8383 as an alternative.

Should I choose POP3 or IMAP?

IMAP if you read mail on more than one device. POP3 if you want everything downloaded to one computer and off the server.

Do I need to enable authentication for outgoing mail?

Yes, always. It is the commonest reason mail receives but will not send.

Can I use the mail app on my phone?

Yes. The built-in app on any phone or tablet works, as does any IMAP app from your app store.

mail.YOURDOMAIN.com, since VPS and dedicated customers run their own mail installation.
