Re: Email sending problem -- any Google Relay experts here?

SUCCESS!

ADDENVVAR ENVVAR(QIBM_SMTP_RLY_TLS_FIRST) VALUE('YES') LEVEL(*SYS) (a suggestion from Mr. Seeberger, in the IBM Community) was the last piece of the puzzle. I also had to cycle the SMTP server; it obviously picks up the environment variables at launch, rather than "on the fly."

A test message just went through!

So to summarize:
1. Make sure both environment variables mentioned by Mr. Seeberger are set, and that the SMTP server was launched after setting them.

ADDENVVAR ENVVAR(QIBM_SMTP_RLY_TLS_FIRST) VALUE('YES') LEVEL(*SYS)
ADDENVVAR ENVVAR(QIBM_SMTP_SERVER_PORT) VALUE('587') LEVEL(*SYS)

2. Make sure the *SYSTEM cert store trusts all the standard certs, and the certs returned by QMGTOOLS/GETSSL as well.

3. Make sure the Google Relay is accepting connections from the IP address whence it sees your traffic originating.
