Subject: 29.1; smtpmail-send-it fails to authenticate using auth-sources
Date: Wed, 18 Oct 2023 08:17:07 +0200
When sending an email with 'smtpmail-send-it' the function 'smtpmail-try-auth-methods' fails to find the matching entry. Using 'edebug' I've found that the reason is this piece of code where the 'port' is converted to a string (smtpmail.el.gz:533-536):

'(setq port
	(if port
	    (format "%s" port)
	  "smtp"))'

When the 'port' is later passed to 'auth-source-search' on line 541 it fails to find any matching entries since ':port' is matched as a number, not a string. If I remove the above piece of code, so that 'port' is never turned into a string, sending the email works as expected. Maybe the best solution is to make 'auth-source-search' match both numeric and string values, at least for the ':port' argument.

SMTP session trace:

Thanks.

I guess I'm missing something, because I use smtpmail with
authentication and a specific port all the time without any trouble.
So maybe show the entry from your ~/.authinfo?

Also, can you point me to the place where you see that port is matched
as a number?  See also bug#55199, where a similar problem was fixed,
and the fix should be in Emacs 29.1.  Maybe you have a stale
auth-sources.elc?

Thanks, I'm therefore closing this bug.

If I remove the above piece of code, so that 'port' is never turned into a string, sending the email works as expected. Maybe the best solution is to make 'auth-source-search' match both numeric and string values, at least for the ':port' argument.

Indeed seem to have been a stale auth-sources.elc file. I recompiled the file and now everything works as expected. Thank you for your quick response, and sorry for taking up your time!
