Any bounce message would go to the email address specified as the sender of the outbound email. That might, or might not, be the email address you expect it to be. Make sure that the FROM: email address (and REPLY-TO:) show the correct mailbox address; I found that by default, when I sent email from a user account, it was sent via the Administratorâs mailbox (and badly, since it FORGED the senderâs email address even though it was sent from a different mailbox). In this situation, a bounce message would probably go to the Administratorâs mailbox, not the userâs.
Try sending an email from SuiteCRM to a personal mailbox, and see what it shows. (You should âview full headersâ or âview message sourceâ to see the actual source mailbox, in addition to the âfromâ and âreply-toâ addresses which are normally visible.)
Then reply to that email from the personal mailbox, and see if that reply is retrieved by SuiteCRM when you tell it to check for mail.
Within SuiteCRM, the âinboundâ (IMAP/POP3) email settings must be separately configured, from the âoutboundâ (SMTP) email setup ⌠for every mailbox and each user (so thatâs 2 places to configure the settings for each user, plus 2 more places to configure the settings for the Administrator).
Also note that by default, SuiteCRM only retrieves emails from the Inbox, Trash, and Sent folders â so it wonât pick up emails in the âSpamâ or âJunkâ folder (which is where some âbounceâ messages might be placed) unless you configure it to retrieve mail from that IMAP folder.
Another issue: check if inbound email to that mailbox is being forwarded to a different email address. Iâve configured our SuiteCRM installation so that outbound emails from the system are sent as "system@example-domain.com" but I configured that mailbox so that incoming emails are forwarded to my mailbox, so I donât have to separately check multiple mailboxes for administration-related email. (This is probably not a wise tactic if you have many users AND use the default SuiteCRM settings, which generate emails for each âassignmentâ to a user.)
Note also that depending on the configuration of your outbound mail server, it might make multiple delivery attempts before âbouncing.â And of course, itâs conceivable that your outbound mail server could be configured to not generate bounce messages at all.
And of course, make sure that the destination email address really isnât valid, and the receiving mail server is generating a âpermanent errorâ rather than a temporary error (mailbox not currently available due to backup process, or mailbox full). I used f87yaf79q43874ytdfughsdfljkghw58t7htftkgjh@gmail.com and gmailâs server responded with â550-5.1.1 The email account that you tried to reach does not existâŚâ which was dutifully sent by our mail server to the source mailbox.
