Frequently Asked Questions About Email
Use IMAP if you want to read email on multiple devices. IMAP synchronizes your inbox, sent items and folders between all your devices. POP3 is only useful if you want to archive emails locally or have limited server space.
Yes, most hosting providers offer webmail via your browser. Go to webmail.yourdomain.com or mail.yourdomain.com. Handy for on the go or as backup.
For IMAP use port 993 (with SSL). For SMTP (sending) use port 587 (with STARTTLS) or 465 (with SSL). Never use unsecured ports like 110 or 25.
Yes, always. SSL/TLS encrypts your email traffic so no one can read along. Without encryption, hackers can intercept your password.
This can be due to missing SPF, DKIM or DMARC records on your domain. Ask your hosting provider to set these up correctly. Sending large volumes of email can also trigger spam filters.
