[Pkg-exim4-users] How to Connect to smtp.gmail.com with different login/password pairs

[Sébastien Hinderer]

Dear all,

Showt version: is it possible to use different login/password pairs in
different (manual) routers that connect to smtp.gmail.com and,
if yes, how, please?

Explanation: I have several email addresses and for better account
separation / isolation I would like to use the right smarthost for
each account. I thus define one router per account and it works well,
except in the following case.

I have two GMail accounts: a personal one (personal at gmail.com) and one
because the company I am working for has its emails hosted by GMail
(professional at company.com). In the two cases the e-mails need to go through
smtp.gmail.com (smarthost) but what needs to change is the login
and password used to connect to it, so that if I send e-mails from my
perso at gmail.com address I log to smtp.gmail.com with htis address as the
login and the corresponding password, and, similarly, if I send e-mails
with my professional at company.com address, the associated credentials
(rather than the personal ones) are used to connect to smtp.gmail.com.

With the passwd.client method only one login / password pair can be
associated to each host, so it is not expressive enough.

I looked up Exim's documentation for a way to override the login in each
router but couldn't find a way of doing that either.

Help on this would be warmly appreciated. Either a solution, or a
redirection to upstream.

Many thanks in advance,

Sébastien.
