Qmail service not working anymore.

I am having some troubles with my qmail using SMTP routes via sendgrid. I have talked with their support and they do not see the server trying to sign in. I get this error

delivery 11: failure: Connected_to_108.168.190.108_but_sender_was_rejected./Remote_host_said:_550_Unauthenticated_senders_not_allowed/

I used the qmail setup here
https://sendgrid.com/docs/Integrate/Mail_Servers/qmail.html
I have tried removing and reinstalling qmail and installing the patch listed here
http://notes.sagredo.eu/node/84
I also did the telnet test that was listed here
https://support.sendgrid.com/hc/en-us/articles/200182038-Testing-your-connectivity-to-Sendgrid-s-SMT
and the test passed with the same username and password I am using.
I would love to get this working and if anyone can help I will be very thankful.

Hi John_waddle

Welcome to IW forums

If I understood your post correctly, you need to send the user credentials with the route.

It will be tommorow when I’m back to look it up, or you could search the forum as it has already been posted I believe, but could be wrong sorry.

You could also try to whitelist your IP on the sending server

I hope that’s alright and hopefully, another user may post

Many thanks

John

I do send the username and password using the following in SMTP Routes on the MTA SMTP Options page

:smtp.sendgrid.net:587|username|password

Good news!
I got it working. My boss changed the name of the SMTP service to HOLDSMTP then when he changed it back it broke the patch. I pulled my from my backup then reinstalled the patch and everything is working.

Hey john_waddell,

Can you give me more description on

Im trying to do the same except with AWS SES, weird thing is i could send it via the mail command, but no email gets sent from MTA or Web Contact forms.

It seems to me that Gmail is not as effective as it used to be. Why don’t you switch to newer analogues of this program? For example https://www.massmailsoftware.com/emailservice/ . They have much more filters and messages to clients come more often (and do not get into spam)
