Mail.com SMTP, IMAP and POP3 settings
mail.com is the English-language mailbox of 1&1 Mail & Media, and it hands out addresses on more than 100 domains such as email.com, usa.com and lawyer.com. The catch for anyone wiring up a mail program is that POP, IMAP and SMTP are Premium features: a free mail.com account cannot connect an external client at all, whatever settings you type in.
For incoming mail, use the IMAP server imap.mail.com on port 993, or POP3 at pop.mail.com on port 995. Pick the exact values from the tool above and copy them straight into your mail client.
Checked against Mail.com's own documentation: support.mail.com. Ports and limits change, so check there too if something will not connect.

What to enter as your Mail.com username and password
Wrong credentials, not a wrong port, are the usual reason a Mail.com connection fails. These are the exact values to type.
Your full mail.com address on whichever of the 100+ domains you chose, for example name@email.com
Your mail.com Premium account password, or an application-specific password when two-factor authentication is on

The exact path through Mail.com's own settings, in order.
- 1
Check the account is on mail.com Premium
mail.com states that 'the use of POP, IMAP and SMTP are mail.com Premium features only'. A free account is refused at the server no matter which hostname or password you enter, so upgrade first.
- 2
Turn POP3 and IMAP on
In the mailbox go to the Email tab, click Settings, click POP3 & IMAP, tick 'Enable access to this account via POP3 and IMAP' and click Save. It is off by default.
- 3
Create an application-specific password if 2FA is on
Log in on the mail.com website, click the profile icon at the top right, click Security Options, then Manage application-specific passwords, then Create new application-specific password (the account portal is account.mail.com). It is shown once, so copy it straight away.
- 4
Enter the incoming server
IMAP is imap.mail.com on port 993 with SSL, or POP3 is pop.mail.com on port 995 with SSL. Port 143 is unencrypted by default and needs STARTTLS turned on.
- 5
Enter the outgoing server
SMTP is smtp.mail.com on port 587 with STARTTLS, or port 465 with SSL. Switch on outgoing-server authentication and sign in with the full address, whichever mail.com domain it uses.

Which port should you use for Mail.com?
STARTTLS on 587 (recommended) or SSL/TLS on 465.
STARTTLS
Starts as a plain connection, then upgrades to an encrypted one. The modern standard for sending.
SSL/TLS
Encrypted from the first byte. Widely supported and a good choice when 587 is blocked.
Plain SMTP
Meant for server-to-server relay. Home networks and cloud hosts block it, so do not use it to send from a client.
Why your Mail.com connection is failing
The failures people actually hit with Mail.com, and what fixes each one.
mail.com restricts POP, IMAP and SMTP to Premium accounts. No settings change gets around it; the account has to be upgraded, or you keep using the web interface and the mail.com apps.
mail.com turns the POP3/IMAP setting off automatically for security reasons when the protocol has gone unused for a longer period. Log in on the web, go to Email, Settings, POP3 & IMAP, and tick the box again.
That pairing is wrong and comes from copy-paste settings sites. mail.com documents IMAP on 993 with SSL and keeps 465 for SMTP with SSL.
Type the address exactly as it was issued, for example name@usa.com or name@consultant.com, as the whole username. The servers stay imap.mail.com, pop.mail.com and smtp.mail.com for every mail.com domain.
With 2FA active, mail.com wants an application-specific password stored in the client one time. Create one under Security Options, Manage application-specific passwords, and paste it in place of the account password.
Mail.com sending limits
mail.com's product page gives 30 MB for free accounts while its Premium help page says a free account may only be warned above 50 MB, so treat 30 MB as the safe free ceiling; no daily, hourly or recipient number is published, and external client access is Premium-only in any case.
Max attachment
30 MB on a free account, up to 100 MB on Premium
Mail.com quirks by mail client
Outlook
mail.com's own Outlook walkthrough adds a step for Outlook 2010 after setup: open Account Settings and map the Sent Items and Deleted Items tabs onto the mail.com Sent and Delete folders, because that version does not link them by itself.
Sending cold email through Mail.com
Varies by account; free accounts have low daily caps. Sign in with your full mail.com address and account password. IMAP access is a Premium feature on some plans.
Those caps make single-mailbox sending fine for personal mail but a poor fit for cold outreach at volume. Emailchaser spreads sending across warmed inboxes and manages deliverability, so you can scale without burning Mail.com accounts.

Setting up more than one mailbox? These sit in the same category as Mail.com.
Common questions about Mail.com SMTP settings
What are Mail.com's SMTP settings?
Mail.com's outgoing (SMTP) server is smtp.mail.com. Use port 587 (STARTTLS) or 465 (SSL/TLS). STARTTLS on 587 (recommended) or SSL/TLS on 465. Sign in with your full email address and password (or app password).
What is Mail.com's IMAP or POP3 server?
Mail.com's incoming IMAP server is imap.mail.com on port 993 (SSL/TLS). If you prefer POP3, use pop.mail.com on port 995.
Which port should I use for Mail.com?
Use port 587 with STARTTLS wherever it's offered, it's the modern standard for authenticated sending. Port 465 with SSL/TLS is a solid alternative. Avoid port 25, which most networks block for client sending. Mail.com's recommended value is above.
Why won't my Mail.com SMTP connection work?
Check authentication first: Sign in with your full mail.com address and account password. IMAP access is a Premium feature on some plans. No separate app password is required, but POP3/IMAP must be enabled in your mail.com settings. Then confirm the host, port and security method match exactly, a 587/SSL or 465/STARTTLS mismatch will fail to connect.
Can I send bulk or cold email through Mail.com?
Not at scale. Varies by account; free accounts have low daily caps. Providers throttle bursts to fight spam, so pushing cold email through one mailbox hits limits and wrecks deliverability. High-volume outreach belongs on dedicated infrastructure that spreads sending across warmed inboxes, which is what Emailchaser does.
I have a free mail.com address. Why will no mail program connect?
mail.com sells POP, IMAP and SMTP as Premium features, so the server refuses a free account whatever hostname, port or password you enter. The web interface and the mail.com apps carry on working normally. Upgrading to Premium is the only route to using Outlook, Thunderbird or Apple Mail with the address.
My address ends in @usa.com, not @mail.com. Do I need different servers?
No. mail.com issues addresses on more than 100 domains and they all run through imap.mail.com, pop.mail.com and smtp.mail.com. Only the username changes: enter the address exactly as issued, for example name@usa.com.
Why did my mail program suddenly stop collecting mail from mail.com?
mail.com switches the POP3/IMAP setting back off by itself when the protocol has gone unused for a longer period, as a security measure. Log in on the web, open Email, Settings, POP3 & IMAP, and switch it on again. Your client settings are still correct; only the server-side toggle changed.
