I'm having trouble sending email through stunnel with our customer service email address. We use google premium services for our hosted email. I can send through stunnel using my own personal account, but when I switch to the cust service account, I get the error:
"Failed to send an E-mail through the specified SMTP server [127.0.0.1]: The SMTP server requires a secure connection or the client was not authenticated. The server response was 5.5.1 Authentication Required."
And yes, I double/triple checked credentials and can login through the gmail interface with them just fine. I also tried changing the password to a strong password which did not help.
gmail settings in stunnel.conf: [gmail-smtp] client = yes accept = 127.0.0.1:259 connect = smtp.gmail.com:465
I also tried port 587 but that produces another error: "Failed to send an E-mail through the specified SMTP server [127.0.0.1]: Failure sending mail."
Any ideas?

My college recently changed its email to google, and rather than using smtp.gmail.com for a regular gmail account, it uses the special name that is mapped to a google server.
[gccpop] client = yes accept = 21995 connect = pop.guamcc.edu:995
[gccsmtp] client = yes accept = 21465 connect = smtp.guamcc.edu:465
Perhaps you have a similar set of names you need to use. I have other lines for my regular account that uses gmail.

Good idea. I tried using smtp.ourdomain.com, but got another error saying the address was rejected. Don't think that's it.
So far, what works: My User Account: Both ports 465 and 587. Also tried changing my password to the same password as the account that's failing, and that works just fine, so it's not a password formatting issue Customer Service Account: sending from Thunderbird using smtp.gmail.com and same credentials (not through stunnel)
What doesn't work: Customer Service account: ports 465 and 587 through stunnel tried putting this account in same gmail group. Even tried elevating to super admin in case it was a gmail permissions issue. Another account in the IT group
So stunnel works for my account, but not for others. Other accounts can send via smtp SSL/TLS through thunderbird.
Really baffled here.

I think I've narrowed down the problem to our local ERP system (the originator of the emails). I believe the problem was the length of the email address. The addresses I tested that failed were both >30 characters. I've now tested 2 addresses of <25 characters, and those have both worked fine. I don't have visibility from the ERP to see what it's passing, but I'm guessing it's truncating addresses.

Good idea. I tried using smtp.ourdomain.com, but got another error
saying the address was
rejected. Don't think that's it.
In the email client users fields are you including the @address with the name as well as the user name.
Testing from the command prompt telnet 127.0.0.1 21995 Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. +OK Gpop ready for requests from 202.128.xxx.xxx to6pf17637891pac.24

Those are the ports that I am using for connection to the gmail accounts for the college, so it shows the connection is made, and then the rest is the email clients issue.
So far, what works: My User Account: Both ports 465 and 587. Also tried changing my
password to the same
password as the account that's failing, and that works just fine, so
it's not a password formatting
issue Customer Service Account: sending from Thunderbird using smtp.gmail.comand same credentials (not through stunnel)
What doesn't work: Customer Service account: ports 465 and 587 through stunnel tried putting this account in same gmail group. Even tried
elevating to super admin in case it
was a gmail permissions issue. Another account in the IT group
So stunnel works for my account, but not for others. Other accounts can
send via smtp SSL/TLS
through thunderbird.
