Description

When trying to activate sending mail via SMTP with the following configuration:

[mailer]
ENABLED = true
HOST = mail.host.com:587
FROM = no-reply@host.com
USER = no-reply@host.com
PASSWD = $password#

I get the error: gomail: could not send email 1: Auth: 535 5.7.8 Error: authentication failed:

Solution

I have special characters in the SMTP password ($ and #). Quoting the password:

PASSWD = `#password$`

was the solution.

I just want to post the solution if anybody has the same issue. Also I would ask if this should be documented in the app.ini documentation. I can imagine that similar errors can occur with the database-password.

That would be good to document that in configuration cheatsheet and/or app.ini.sample

I've made a pull request addressing this issue in sample.app.ini and it's documentation.

I just ran into this myself, except I never edited the config app.ini manually, it was done during the setup phase. It seems that (in install.go) we should write out a value surrounded by backticks to prevent this.

The simplest change would just be to backtick-surround mailer.PASSWD, but that strikes me as a band-aid. Perhaps the install code should be modified to use some helper that detects special characters (wrapping SetValue()) and auto-wraps them.

I'm happy to put together a PR and test if that sounds sane.
