Hi Marjj, is this problem in the Firefox browser or in the Thunderbird email program? If it's Thunderbird, a moderator can move your question from Firefox to Thunderbird.

It is on my Thunderbird email program. How do I contact a moderator?

Moving to Thunderbird.

[https://www.telus.com/en/ab/support/article/set-up-email-android-phone-tablet Telus] has a few suggestions for the outgoing server: smtp.telus.net on port 1025, SSL/TLS security, normal password authentication, User name = full email address. [http://business.telus.com/en/business/support/global/how-to/how-to-set-up-your-email-on-any-computer Yet another page] suggests the connection security should be none on port 1025. In that case, authentication = password transmitted insecurely. [https://www.telus.com/en/ab/support/article/set-up-telus-email-windows-live-mail or] (not recommended), smtp.telus.net on port 465, Connection security = none, authentication = password transmitted insecurely, User name = full email address. Port 465 usually has SSL/TLS security, and this [http://forums.mozillazine.org/viewtopic.php?p=14756282#p14756282 works for one Telus user]. A setting with no security may work if you are always connected to the Telus network, but SSL security means it will work even when you're on a different network, e.g. sending from a mobile device.

Thank you so much.
