If you can receive emails but are unable to send them, try the following steps to help resolve the issue:
1. Try sending from webmail
Login to your Webmail System and try sending an email from there. If it works, the issue is likely with your email client settings. For those receiving email services from, use https://webmail.isgdev.com to access the system.
2. Check your outgoing (SMTP) mail server settings
Double check you have entered these values correct, as even a small typo can cause sending issue. For those receiving email services from us:
- Server: mail.isgdev.com
- Port: 587 if using STARTTLS (preferred) or 465 if using SSL (alternate)
3. Enable SSL (Secure Connection)
If your email application has a setting for Security Type or SSL, make sure it is enabled. Only secure (SSL) connections to the outgoing mail server are allowed by our systems (and many providers today).
4. Enable outgoing mail authentication
If your email app offers an option for authentication when sending mail, it must be turned on. Select password authentication if multiple methods are available.
5. Verify outgoing username and password
Many email clients let you use the same credentials for both incoming and outgoing mail. If this option exists, select it. Otherwise, enter your full email address as the username and your email account password for the outgoing mail server. Some apps have separate fields for outgoing mail credentials, so even if you entered them for incoming mail, you might need to enter them again for outgoing mail.
Additional Tips
- Look for error messages or codes
If your email client shows an error when sending mail, note the exact message or code which can help us work with you on resolving the issue. - Try sending from another device
This can help determine if the problem is with your email account or the specific app or device you are using.
