Cannot send outgoing email

[Bycor]

As of yesterday, suddenly cannot send mail, although am still receiving mail.

Mac OS 10.11.6; Apple Mail 9.3.

Coincidentally -- or not? -- can no longer receive or send email from my iPhone when wifi is enabled.

Help?!

What service do you use for email?  If Telus.net, have you confirmed the SMTP settings?

[Bycor]

Thanks for your response!

Account type is POP

Outgoing mail server: mail.telus.net

Port: 995, using SSL

Can you try using port 1025 as your outgoing SMTP server port?

[Bycor]

That worked! I wonder why the port # would change? That's ok -- you don't have to answer that!

Many thanks!

There's a partial explanation at this link.

Port 1025 became the one Telus now uses for all SMTP traffic whether from within it's network or outside. Previously users would be able to send mail when connected to legacy ports only when connected to a point on the Telus network. For instance, sending mail from my laptop at my brother's place (Shaw) would not work, but if I connected to a friend's (Telus) Wi-Fi network - all the pent-up emails sent. The use of port 1025 with SSL has fixed this issue at least for the most part!

That solution doesn't work. I can only send using cellular not using wifi. Don't call the Telus techs just spent 2 hrs on the phone with 4 different techs telling me to do,the same thing over and over,

Care to provide a bit more detail as to the settings you have, and the error messages you receive?
