ISP IMAP acc't(s) send mail problem [solved]
Posted: Mon Apr 12, 2021 1:16 pm
Greetings! Long time user of POP Peeper (free) & it has served me well for years.
I have 2 virtually identical Win 7 x64 (up to date) PCs w/ POP Peeper installed. Last week, one PC started giving me the following error when sending an email from any of 3 acc'ts. Gmail IMAP configs on both PCs work fine... only ISP IMAP acc'ts on 1 PC fail.
OS: Windows 7 (x64)
POP Peeper: 5.1.1.0
Webmail: 5.1.0.0
SSL: 1.1.1.7
IMAP: 5.1.1.0
SendMail: 5.1.1.0
PPTweaker: 5.1.1.0
Updater: 1.0.0.0
Program folder: C:\Program Files (x86)\POP Peeper\
Data folder: C:\Users\usernameC\AppData\Roaming\POP Peeper\
--- Error ---
ispname - username [1000: IMAP] ['mobile.ispname.net' (993) SSL: 1] [Smtp: 'mobile.ispname.net' (587) SSL: 1] [oauth: 0] [consec: 1]
- Send Mail: Failed to Verify after EHLO
Server Returned: EHLO [external IP] blocked. Please see https://www.ispname.net/support/interne ... rror-codes for more information. AUP#Out-1080 (#501)
which says "This email account has limited access to send emails based on suspicious activity. Blocks will expire based on the nature of the activity. If you’re a ispname customer, contact us to remove the block".
DEBUG steps.
- Tested BOTH PCs. Only one exhibits this issue.
- Assuming a banned/blocked IP, I tried a MAC clone on my router, pulled a new IP & got the same error... on the same PC.
- Called ISP & verified NO blocks on their end. Jumped thru their "hoops"... send via webmail, etc... passed w/ flying colors. "NOT our problem."
- Uninstalled POP Peeper completely on the 'problem' PC & removed ALL profile data. Reinstalled latest/greatest POP Peeper. Cloned a profile from the working PC (too many email acc't variables to re-enter all manually). No change. Same behavior.
- Completely removed ALL antivirus/malware apps from problem PC using their 'clean' tools & reinstalled NIC/network drivers/stack. With nothing interfering w/ the network stack, many reboots, etc... no change. Same behavior.
- Reverted to an earlier version of Pop Peeper... 5.3, I believe... no change. Same behavior.
Having exhausted all the usual remedies, I find my self here. I can provide any additional info you require upon request.
The problem PC is my primary machine & I'd REALLY like to restore things to their previously working state. Hope you can offer a solution?
TIA
