POP3 accounts under external software

[fearworks]

Hi there.

I am facing some issues regarding my POP3 accounts under my CP. It seems that everything is working just fine from the Roundcube Webmail, I might say without any issue at all. But if I try to use any software like Outlook, Thunderbird or even a cell phone to get my emails under my accounts in the server, I can receive emails but I cannot send any email from my server.

I dont know if someone faced the same issue here, but I try to check in the forum for similar posts, somehow I did not found any regarding this issue.

I kindly ask if someone can help me on this. My best regards to you all.

I think there could be a number of reasons why this is happening.

Your firewall might not be set up correctly, you might need to set up SSL/TLS certificates on your server, or you might just not be using the right settings. POP3 and IMAP are only used to retrieve the email messages to your device or mail client, so if you are receiving then you can probably assume POP3 or IMAP is working for you. SMTP is used to send emails, so if you are finding this is not working (apart from when in Roundcube, which is local to the MTA on your server) then you need to look at that protocol, the ports associated with it, which certificates you have set up - if any - and work from there.

It's almost impossible to diagnose a mail issue without information about the server. If I knew your domain and IP info then I would be able to see what ports are listening, if you have certificates, etc. so if you want to PM them to me I don't mind taking a look.

Also, mail clients can offer so many configuration options (for example, on my Android phone, when I add a new mail account, I need to tell it which ports to use for IMAP/POP3 and for SMTP, whether to authenticate, whether to use a secure connection, and so on) that selecting the wrong setup here could lead to problems with sending or receiving.

Of course there may also be DNS issues, but if you are receiving to Roundcube from external accounts, I doubt this is the problem.
