    @aqeelzakir-com said in SPF DNS record (TXT) did not match.:

    Relay error: Connect to port25check.cloudron.io timed out. Check if port 25 (outbound) is blocked
    Email Status is checked every 30 minutes. See the troubleshooting docs for more information.

    See https://docs.cloudron.io/email/#outbound-ports . Basically, your server is unable to send mail because outbound port 25 is blocked. You have to either get it unblocked by talking to your VPS provider or you can set up a relay.

    Expected: v=spf1 a:my.example.company include:_spf.google.com ~all
    Actual: v=spf1 include:_spf.google.com ~all

    If you are going to use a relay, the error above will go away automatically. Otherwise , you have to add a:my.example.company into the SPF record in the DNS.

    @girish said in Improved global E-Mail signatures:

    Is the idea to extend our current global signature to use template/variables (from the authenticated user sending the mail)?

    Practically, yes that would be amazing! Variables I would like to be able to use:

    First Name
    Last Name
    Email
    Company (Could come from the cloudron branding name)
    Job Titles (This would require an addition to the user database
    Profile Photo or image url for static images like logos etc.

    @ccfu The quarantine plugin only dumps the messages into a directory which is not overly useful because there is no UI to manage the quarantine.

    because Cloudron does not provide a way to block or quarantine mails altogether based on central SPAMAssassin rules or sender addresses, as this can only be done using filters on individual mailboxes

    We have global SpamAssassin rules - https://docs.cloudron.io/email/#custom-spam-filtering-rules .

    I want to understand the use case better though. Is the issue here that spam is slipping through the SA filters?

    @alexm said in Spamhouse blacklist:

    I am kind of struggle to understand is it the problem of OVH or the way Cloudron uses this Spamhous open relays?

    VPS providers have a block of IP addresses and they cycle these IP addresses across their customers as VMs keep getting created and destroyed. This means that your IP was used by someone else previously and maybe they sent a lot of spam (an unfortunately common situation). When this happens, spam watchlists like SpamHaus place the IP address in their email blocklist . In some cases, people will wholesale block the entire VPS provider IP address range since the VPS provider is not responding to spam appropriately. There is a lot of unknowns here since all this handling is not "transparent" - an email receiver can use all sorts of blocklist providers and unknown criteria to determine if your email is "spam" or not. They might even block emails by domain name etc.

    Your best bet for reliable email is to sign up and use a relay - https://docs.cloudron.io/email/#relay-outbound-mails . If you don't want to use a relay, you have to be "patient" to give your IP and domain a good reputation . You have to also get your IP/domain whitelisted from the various email block list providers. Most of the email blocklist providers have an online form that you can fill up to prove your reputation.

    Setting up the sieve rule means I have to have the password and set all of that up.

    Using the "mailing list" settings means I don't have to do any of that, don't need to create an inbox, and it doesn't need to be owned by any accounts (and cloudron users with email admin / admin / superadmin can modify as needed).

    So I guess I answered my own question πŸ™‚ I'll write it up. for people who ask in the future. "How do I set up email forwarding to external accounts without having to provision Cloudron accounts" == mailing list.

    @luckow thanks for the SoGo -- looks like that does take care of everything.

    @cylon usually, you can request your VPS provider to open that port and they might if they trust to now spam πŸ™‚

    Alternative is to setup a relay - https://docs.cloudron.io/email/#relay-outbound-mails

    @foliovision it's in https://docs.cloudron.io/apps/#email πŸ™‚ See the note. But to be fair, it's hard to read through all the docs in detail.

    It's the same with SOGo. Use the mailbox name as username and any of the group's credentials as the password.

    If you want to receive email, you have unblock incoming port 25.

    If you just want to send emails, then use a relay as @jdaviescoates suggested.
